Trying to close my MTN contract/account

I have been trying to close my MTN account , I paid off the account on the 02/01/2015 and I was told the account has been closed. End of January I received an invoice. I called 808, holding the line for literally 2hrs at Gateway mall, and I was told they need to look at the account I should call back the next day, i spoke to Nosipho Magaza (credit management) department, I called the next day , it took me over an hour to get hold of her, and she informed me that my contract has been paid off and I do not owe MTN a cent and my account will b updated accordingly.<br> <br> Today, 09/02/2015 came to MTN shop, east rand mall, I am been told that I have an outstanding amount, am trying to get hold of Nosipho again, been seating in the shop for over an hour, still holding the line listening the MTN ridiculous jingle.<br> <br> I am so frustrated, the consultants useless in the shop, 808 service number annoyingly USELESS.<br> <br> Ultimately Ayanda from the credit management department picked up my call, only to tell me that Nosipho is just went out of the office, when I demanded that she gets me someone that can help, Ayanda hung up on me<br> <br> What is this, how is this ok? how does MTN justify? MTN is ABUSIVE
