MTN worst customer services when cancelling, and then they still have the gaul to debit my bank account even though there is no service being delivered

Cancelled contract with MTN in beginning of April 2024 with a Sifiso Shangase of MTN, yet they continued to debit my banking account, After sending numerous emails to Edward Phaka and Allison Hendricks, and in person visits to MTN Herm**** and Caledon, the monies that was debited after the cancellation of the contract is still not been paid back to me. How long are we still to be ********** by the likes of MTN and a clearly faulty and outdated system that cannot even manage to successfully cancel a contract. The router and SIM was immediately switched off, yet, for months afterwards I had to pay for no services rendered and at great cost to myself, travel to branches of MTN to get this sorted. You have now left me with no other recourse than to escalate this issue to the Ombudsman as well as the consumer council to ensure that this ******* activities of yours stop.
