MTN CUSTOMER SERVICE SUCKS!!!

MTN is truely atrocious with customer service. I am a current contract customer and cant wait to get to the end of my contract period to move away from them. My account was in arrears last year and they put me as a default on Transunion credit bureau. I paid up the account in full and it is up to date for 8 months now but they have not removed the listings from the credit bureau. I have called them around 6 times to remove the listing and I cannot speak to their legal department and must go through the call centre and just get reference numbers again and again with no resolution. Reference number *** and *** and then I get told to call legal and they give me these numbers *** and *** which don't go through. MTN SUCKS!!!!! I would rather pay more with Vodacom and get proper customer service!!!
