MTN refuses to cancel contract ***)

I had a contract with MTN. The contract lapsed on the 2nd October 2022. Now, per the contract terms, on the 5th September 2022, I wrote a cancellation letter to MTN to notify them that I am not upgrading nor continuing with the contract. That is I am cancelling the contract as it has lapsed. Mapitso Skhosana from MTN's retention department acknowledged receipt of my cancellation letter. On the 12 October 2022, MTN reactivated the contract and I don't know under whose instructions because I have sent them a cancellation letter on the 5th September 2022. They further claim that there is an outstanding amount of R337.55 which is a lie because that amount was deducted on the 20th September 2022 (and that was the 24th debit order and my contract was for 24 months). The contract cellphone number was ***. MTN must know that they cannot force me to have a contract with them. I will go to my bank and stop all their future debit orders and should they carry on debiting my account *******ly, I will reverse all their debit orders. People must be warned to stay away from MTN. They are ********* and their network is very poor with no network coverage for almost half of the day every day.
