******** debits after end of contract..

I wrote to MTN to cancel my Month to MO th xontract in September and they did not do it. I eventually called and I thought it was done. I tried porting my number to telkom during October 2022 and kept failing. Eventually I went I to MTN Menlyn and they wanted me to pay a pro rata amount of just over R300. The Co sultan confirmed the Contract was canceled. I was able to port within a few days. Lo and behold they have still tried to debit my Account in January and February 2023. When I reversed those debits because I have no contra t with them.. I am now reported as havi g missed payments and my credit report is affected. They do not answer phones.
