Supersonic is the Worst ISP in SA.
Support is literally non existent. I have been trying to reach them for a week. They have the worst Whatsapp bot in the world and when you finally reach a person, nothing gets done.
Before you sign up for any Supersonic services, do yourself a favor and quickly read a few reviews. There is a reason they have a 1 star rating on most platforms.
Supersonic has an average of 1.2 star out of more than 6000 reviews on HelloPeter.
There are a lot of better ISP’s out there, you deserve better…
Recommendation: Steer clear of Supersonic. You will regret using them.

Supersonic
I would like to warn other potential customers that the service you receive from Supersonic Fibre and MTN Fibre is absolutely pathetic.
I've requested a month to month fibre package of 250mbps. Metrofibre quickly had the line and modem set up, and then the wait started to get the router from Supersonic.
Getting no feedback from Supersonic, I tried logging tickets and raising queries with the call centre. Eventually it got delivered with a message that my order is complete and they'll be in contact soon to send someone to set up the router.
This is the day they sent me the first invoice and started charging for usage. I set up the router but my speed was capped at 5mbps.
It's now been an additional 8 DAYS after logging many tickets, countless calls and being put on hold to try and reach the support / second line support teams (who never answer or call you back), my speed is still limited and I receive no feedback or updates. This client service is so bad it feels like a scam.
Supersonic, I informed you 3 DAYS ago that if a technician is was not here by the end of that day I'm cancelling all services. I did get a follow up call the next day where they shared an adress and details of another client with me and eventually realised that they had the wrong profile open.
2 DAYS ago I've requested that you please come and collect your router and cancel my contract. If I get charged anything on my accounts I'll inform the bank that it's fraud. I'll switch to Metrofibre since I hear their service is actually good.
The day after posting my first review I got this message: "Dear Valued Customer, Please be advised that the debit order for your Supersonic subscription was not successfully processed today, due to unforeseen circumstances.Rest assured, the transaction will be processed tomorrow, 2 February 2024. We sincerely apologise for any inconvenience caused. Kind regards, Supersonic"
Your social media team have asked for my details on every post (3 DAYS in a row) and informed me that they will get the support team to contact me, and logged tickets for the error. Guess what... Still more unattended tickets and no call backs

Billing, cancellation, service, everything
Never ever go into business with this service provider. I had an lte line with them that worked perfectly in 2022, after the sales pitch knocked me off my feet about their air Fibre, I upgraded or should I say I thought I upgraded. The Installation was done after 20.00 at night beginning February 2023. After load shedding that night it never worked again. Every single day I called and created never ending tickets, the technician came through so many times, I didn't even use the service for 24 hours. I again make endless calls for the service to be canceled. We then used Telkom lte. Next best they were debiting my bank account so I followed up on both cancellations, they were not done. I made arrangements with them to collect their sir Fibre, which they did. I went personally to their Mtn offices on 14th Avenue to deliver all 2 routers and chargers, luckily I took a pick off the finalised paperwork. I received a call from a guy, Jaydee who said my matter would be resolved, thst clearly I did not owe them and all the apologies under the sun. His call finally gave me peace about this service provider. Kanto Every month to date they kept debiting me and I reversed the debits. In September I decided to go back to their offices, only to be shocked told that I now owe the approximately R8000, the routers I tokk personally to their offices, only 1 was booked in. I stayed there for hours demanding to speak to a manager, nothing. Eventually a guy Nelson Hart came to assist with another lady Kgomotso. Explained that the lady that worked on my account resigned she had not ever looked at my account and just referred it for me to pay. The 2 made promised the matter to be resolved within 48 hours. Today is 27 October, my emails are no longer being responded to. Last I was told the matter is at Exco. Stay far from Supersonic they will make your life a misery
Desired outcome: Clearance letter, confirmation letter that I have no dealings with Supersonic
Is Supersonic Legit?
Supersonic earns a trustworthiness rating of 91%
Highly recommended, but caution will not hurt.
We found clear and detailed contact information for Supersonic. The company provides a physical address, phone number, and email, as well as 3 social media accounts. This demonstrates a commitment to customer service and transparency, which is a positive sign for building trust with customers.
Supersonic.com has a valid SSL certificate, which indicates that the website is secure and trustworthy. Look for the padlock icon in the browser and the "https" prefix in the URL to confirm that the website is using SSL.
Supersonic.com has been deemed safe to visit, as it is protected by a cloud-based cybersecurity solution that uses the Domain Name System (DNS) to help protect networks from online threats.
Supersonic as a website that uses an external review system. While this can provide valuable feedback and insights, it's important to carefully evaluate the source of the reviews and take them with a grain of salt.
We looked up Supersonic and found that the website is receiving a high amount of traffic. This could be a sign of a popular and trustworthy website, but it is still important to exercise caution and verify the legitimacy of the site before sharing any personal or financial information
However ComplaintsBoard has detected that:
- While Supersonic has a high level of trust, our investigation has revealed that the company's complaint resolution process is inadequate and ineffective. As a result, only 0% of 14 complaints are resolved. The support team may have poor customer service skills, lack of training, or not be well-equipped to handle customer complaints.
- Supersonic protects their ownership data, a common and legal practice. However, from our perspective, this lack of transparency can impede trust and accountability, which are essential for establishing a credible and respected business entity.
Incomplete product provided, no client service, billed for service not received, billed for defective router.
*RE: Incomplete product provided, No client service, billed for service not received, billed for defective router.*
Subscribed and received an *incomplete and used router*. Despite attempts to get Supersonic to rectify the situation, couldn't utilize the service. Logged complaints through various Supersonic contact points, but received absolutely no support – not just lackluster, but *complete absence of support*. None. It's a black hole of frustration.
Furthermore, I was billed twice for a service I was never even able to access. Astonishingly, upon canceling my account due to frustration, they took it a step further – instead of addressing the issue of the defective router and collecting it, *THEY INVOICED ME FOR THE FAULTY ROUTER I HAD BEEN COMPLAINING ABOUT!*
This company's behavior is a disgrace; their conduct verges on the unethical and resembles a scam; they're clearly unable to provide the service their client's pay them to deliver.
They've fail in fulfilling the fundamental roles of an ISP: *PROVIDING* *SERVICE*, support, and *functional INTERNET* to paying customers. Their inability to meet the basic responsibilities of their business is both outrageous and abysmal.
I strongly advise avoiding them at all costs, unless you enjoy disputing charges with your credit card vendor.
Desired outcome: Refund all automatic deductions for services that I was never able to utilize.Refund the automatic deduction for the DEFECTIVE ROUTER THEY CHARGED ME FOR! Retrieve their used and incomplete router, with expenses covered by them.
305 full flavor 100s cigarettes
I am providing a receipt for purchase on August 3, 2023 for three cartons of 305 Full flavor 100s cigarettes. Try to smoke them they had a bad flavor like they were rolled with cigar tobacco, and they tasted like paper. Took them back to the clerk and he said that’s how they were stored and take them back to the owner the next day. I showed him that the...
Read full review of SupersonicService and Unauthorized debiting of my account
In 2020 we decided to take out a Supersonic plan however we cancelled it and informed Supersonic. Since then every now and again my bank account is debited via debit order with unusual amounts. We received no service as we cancelled almost immediately and Supersonic has fetched their router. Each time I contact them when I find my bank account debited I either get told that they are looking into it or the issue is resolved or they have a problem and then without any communication 3years later my bank again gets debited. I am fed up
Desired outcome: I wish that they stop debiting my account as I am not receiving service from them and cancelled long ago
Terrible. Wish I never heard of this company
No internet service for 5 days.
No internet service on Sunday, 14 May. Put in call to service center on Sunday. On Monday put in several calls to service center and contacted service center via whatsapp. Service Center tried to help with no successful internet connection. Escalated the issue to supervisor, but issue was not solved at all. Engineer contacted us on Monday night, but he only works afternoon and nights. Since Tuesday (Tuesday, Wednesday and Thursday) every afternoon late we receive calls from engineer requesting us to reconnect and test - it is Friday, 19 May still no internet. Paying now for service I do not receive! Supersonic indicating issue is with Evotel. I also phoned Evotel on Monday, 15 May, Evotel indicating the issue is with Supersonic.
Several re-configurations were done - no positive outcome, we still do not have any internet service. Between Evotel and Supersonic they cannot sort out the issue.
Desired outcome: I would like to have the internet connected and working all the time.
No service and resolution on outage
Discover my Fiber is out Monday morning the 1 May around 10am. I tried contacting the call Centre but after 35 min hold I asked for call back. I loged a request as well after ending call for a call back, no joy. Then I started with the WhatsApp bot, after messaging they say someone wil chat to me shortly. After waiting two hours I tried again, even tried to log incident with OpenServe but is not allowed, only ISP can
Message they know there is some issues on Openserve customers and they working on it.
9:45 pm finally get some one on WhatsApp sadly gives me standard messages and can’t provide reason or ETA Tuesday 10:15 got a call back saying Randburg is impacted, they found the problem and work in resolving. From 3pm I am trying again with full process and no response, I now give up 10:10pm
Did receive their invoice though 1 May
Desired outcome: Beter service, getting info of problem and when it will be resolved
Internet not connecting
My internet is not connecting I called the customer care it was a nightmare to find an agent to assist it took me about two days to get an agent, the agent told me I joined another internet provider of which it was not true I never joined any internet provider and she said the problem is with open serve the open serve agent came all their lights on their router was normal and they advised me to call supersonic I’m struggling ever since with no internet still the service is very bad. Can someone help me get my services back.
Desired outcome: Can I get my services back asap
Fibre package
I had a fibre package installed in February this year for the amount of R394 per month which I am still using, what worries me 2 months later I created a online account on their site and was amazed at an amount showing R2400 outstanding, I called the call centre and explained a lady told me not to worry as this is a error as I'm a vuma tell client using the supersonic service, I checked again 2 months alter the amount was now more, I called a million times asking for a letter stating it is indeed a error I'm still awaiting this letter and the amount is now over R7000 I am paying the R394 per month though, I'm just scared if I need to cancel they will tell me to pay this amount that I don't know what it's for before I can cancel, this is tiring and seems cannot be resolved no matter how much I tried.
Desired outcome: I need supersonic to contact me and sort this problem out
Cancellation request
I requested cancellation of the service and I was advised that I cannot cancel before 6 months and if I do I will be charged a cancellation fee of R600 along with a fee of R250 for the courier to collect the device from my home, this a month to month subscription and why should I pay fees if I am not happy with your product and I found something that works better for me. Clearly this is a rip off and I am very unhappy. The agent advised me that I have 7 days in which to test the product and if I am not happy I can return it but its only been 10 days and I was advised that I am liable for the R600 + R250 fee because its been 10 days. RIP OFF
Connecting to the internet.
In March I asked them for connection to their internet. You said that it will take from 7 to 10 days. It is now JUNE. nothing happened. I phoned every week. At last you delivered a rooter, about 6 weeks ago. That's all. This morning an agent told me that I must just wait, someone will contact me. Will you please look into the problem.
