Worst Service and Network

I wish I could give a -5 rating to CellC, I have tried to cancel my CellC contract that I was told was on a month to month basis since I upgraded it to the 1T data line (01.04.2020), They still deduct money after I mailed them aswell asking for my contract to be canceled 29 March 2022 and till now they don't cancel my account after multiple attemps has been made, they still deduct money for something I have not used since March's attempt on canceling it.They have told me that it was now a full 24 months contract and I am liable to pay a penalty fee for canceling early or continue to pay for 9 months till contract comes to an end. Which is unfair since I don't use it. On my statement it still however show that it is on a month to month basis, when I called the customer service they said it is new terms and conditions that stated all month to month should go to 24 months packages, but I did not agree or sign anything on that terms and conditions. Now when I want to use my cell c app it takes me to accept the new terms and conditions and not let me use the app as previously, I won't accept that since I canceled my contract. Who can help me or what can I do to get this fixed?
