MTN cannot provide a simple service

Dear MTN, I have been having so much of problems ever since we had taken out an MTN contract with Nashua Mobile.<br> <br> After being notified that Nashua Mobile have closed down, the problem has just escalated. Every month there is an sms sent to the contract number saying that we are in arrears and thereafter the line is suspended! We must sit for hours holding on the phone just to explain that we did make payment and then we are reconnected. Then we must also further send proof of payment to you! Do you know how much of a inconvenience your are putting us through?? It is not my problem and fault that Nashua does not communicate the payments to you. I even starting making payments directly to MTN's Absa account and still we are having a problem! Could you please resolve all your contractual issues with Nashua and not make it the customers problem. I simply took a service from you, pay you on the agreed date and thats it! <br> <br> I was even asked to request refunds from Nashua. I cannot do this as i was contractually and still am obligated to pay them. You (MTN) need to resolve your billing system.<br> <br> Kindly treat this as a Priority
