CellC reaping me off and refusing to cancel contract with them.

My name is Nombali Nzimande, last year I phoned Cell C trying to find out when is my termination date for the Sim contract that I have with them, and I was notified that it's in February 2023.end of January 2023 I made several calls in hope of terminating my contract with them and the main reason was that CellC has a veeeery bad signal where I reside and I did p Send them messages on the app notifying them with the same problem. Take not that for the past 6 months I haven't been using their services and in January and February I tried calling them for the purpose of terminating the contract but each and every time when they transferring my call to cancellations department the call get cut off and this happened more than three time. Hellopeter please assist as I'm seeing the debt escalating up to R3000 and I don't understand why because they are refusing me to terminate the contract. Prior to that they costed me almost R1500 bank charges on standard bank for bounced amount of R150 every transaction that they made on my account because they would debit on my account even when I had no money in it and this made a huge negative balance on my bank account. Please assist because I've tried to call them to terminate my contract with them but I had not succeeded.

Regards Nombali Nzimande
