Unprofessional

I reguested my contract to be cancelled and requested to keep my number for prepaid use on Feb 2021 and nothing was done after sending 3 emails to customers care and yet it was never cancelled. After I reversed their debit order on May only then they started communicating with me requesting me to make bank deposit. When I question why must I continue paying since I have cancelled the contract, I was only then acknowledged and my matter escalated. But over the weekend I realised my number is completely suspended. They are so *********** and unprofessional. My number is used for my banking and now I don't have any contact. MTN is truly a dissapointment.
