NCC Compaint

I have been put on a month-to-month contract that I DO NOT WANT. I have been trying for 6 months to cancel unsuccessfully. My account is now sitting at over R11 000 and nobody at MTN is assisting. I have logged multiple tickets with legal, credit control, accounts, collections, customer care, and in-store (since November) but to no avail. I do not want this contract. Hence I have lodged a complaint with the NCC as per ICASA's referal.
