MTN bills cancelled contracts

@MTNza your service is the worst. I cancelled my contract in July 2020, and youre still billing me 5 months later despite several calls and visits to your offices. Your staff keep making empty promises to stop billing and to refund all additional billing since that time. I will never recommend MTN to any business or individual considering your lack of professionalism. This is day time *******. Im appalled by your service!
