The cancellation process and the service offered by C-Date is appalling.
I checked past emails for cancellation instructions and the first correspondence I received, from C-Date, was an email demanding further payment, threatening debt collection and court action. I tried to cancel through the cancellation (tab) process on the website, before this, when I had access, to the site and it loaded to a blank page, so had NO means of cancellation before the first email demands. Why should I need to contact the customer services for a failing system?
After the initial email saying they would pass my details to a debt collector, I researched online and found hundreds/thousands of similar reviews and this has raised a further alarm with me.
I will NOT be comfortable to make any form of payment to them, it would lead to further issues, threats, like I have seen in your reviews online and also my direct first hand experience of course.
I have contacted, their bank, Luxembourg police, PayPal, Apple App Store, Google Play store, Action-fraud, your web hosting service and DNS provider, amongst other professional bodies in relation. All this information is available online!
