Impossible to cancel the contract - month to month is a total lie

The onboarding experience was fast, efficient and of an impressive standard. The off boarding experience and cancellation of my account has been absolutely shocking. I cancelled my contract 3 months ago and sent back the router and sim, I got acceptance of cancellation via support, however, I am still being debited R699 a month. I have contacted email support more times than I can remember and have spent many hours on the support contact number with no success (as nobody answers) I can not think of any other way of resolving this matter.

One creative solution I had, which I think I may try, is updating the payment method to my credit card and then reporting the transactions as **********, charging back and hopefully getting Rain blacklist at a bank level to stop them from continuing to rob innocent consumers.

May be worth a try for other desperate consumers.
