Poor Service from MTN for reactivating my line.

I have an existing contract with MTN. I skipped payments and I was notified my line has been suspended. I then communicated with MTN to find out the outstanding balance so I can settle my account. I was given the amount outstanding and I paid it out.<br> <br> I phoned MTN and they confirmed that payment has been received. It's been 2 months since then but my line hasn't been reactivated. When I call the Call Center I'm told to email Collections Admin. <br> <br> Collections Admin reply and say I should call the Call Center because they can't match my details - the same details Call Center can match to my account. Proof of payment was attached to the email but still no progress - going in circles.
