Cell C review: Cancellation of contract results in over 200gb's of pre-paid data being deleted

I cancelled my WiFi [protected]) contract with the full expectation that any contract data would be forfeit at the end of the month.
However, I did not expect the over 200GB's of a pre-paid data purchase (R570.00 = 50GB Day + 50GB Nite per month for 6 months) made on 13 January and valid until midnight on 12 July to be forfeit as well.

29/04/25 20H26 Received a text advising I had 12 731mb of data remaining. This was largely the pre-paid data.
30/04/2025 Contacted various departments within Cell C from 06h26 - all to no avail.
Eventually spoke to Customer Service and logged the data dispute (ref 504300270), told it had been escalated and would be contacted within 2 days.
Also sent an email to Customer Service citing the reference number
It is now 4 business days and now 8 days since this was lodged.
06/05/25 At 10h02 I was asked to provide a screenshot displaying the text and information on the prepaid data and my data would be restored.
This was supplied at 10H53.
The ''agent'' has tried to call me but due to relentless marketing calls from that number - the number is blocked but was unblocked to facilitate him reaching me.
I also provided an alternate number for him to reach me on.
I had to purchase data in order to work.
Despite the assurance from the ''agent'' that on providing the necessary information - my data has not been restored.
I have lost 8 days of the pre-paid data which is not going to be re-imbursed by Cell C.
One would think that when a company has made a blatant error they would resolve the problem as fast as possible and with minimal inconvenience and unnecessary financial outlay by the customer.
Despite more than a few emails today to Customer Service as well as the ''agent' who was meant to restore my data yesterday, I have yet to hear from the ''agent'' at the time of writing despite being assured the ''agent'' will shortly be in contact.
Since I will be at a funeral from 14h00 today, that is undoubtedly when this ''agent'' will attempt to call me and I will be unable to take the call thus leaving this unresolved again till tomorrow.
Salvador Francis will be receiving and email shortly as well.
Clearly the ''agent'' has no sense of urgency or reputational damage.
