HOW MANY MORE COMPLAINTS MUST BE FILLED?

How many more complaints must I file? How many times more do I have to call the call centre before this problem is going to be sorted out? Its been months now that I have been complaining, the only feedback I get is that a query will be logged and someone will get back to me but still NOTHING! Got my monthly airtime on the number in question the 21st and on the 22nd some of my airtime disappeared AGAIN! MTN is quick to cut of services when a payment is late but takes months to sort out a problem like this. I know I am not the only one experiencing this problem as I have spoke to a many MTN users before logging my first complaint. In the accounting profession where I am in time is money and MTN has been waiting my time. After all this time and empty promises not even reimbursing me with the airtime lost will satisfy me. It will definitely take more than that. I will be out of reach until 4pm but will be able to attend to phone calls again after 4pm, if this is not sorted out within 24 hours I will have no other choice but to take it to news papers and if need be I will seek help from an attorney because I am sick and tired of this not being sorted out especially after months!
