Horrible contract experience

Two weeks back I identified that MTN had not debited my account for 2 months. I called Newtown branch to request the bank account so that I can deposit the money directly. The sales rep told me that my account reflect errors and that it shows that my account had been handed to legal department. She said she couldn't identify why it was handed to legal but she will make some follow ups. On Thursday 07 April 2016 MTN suspended my contact number(I couldn't receive nor make any call). I contacted call centre and they said they cannot help me I have to call legal department. They gave me contact details but every time I called , the person attending the call will give me a different number to call. I ended calling 8 different number but still without success of getting hold of legal. I am still disconnected and nobody seems to be able to help me.
