COSTLY NEGLIGENCE FRPM SERVICE PROVIDER

MY PHONE CONTRACT SERVICES WERE SUSPENDED IN 2013 ALREADY BECAUSE OF AN OUTSTANDING BILL. HOWEVER I HAVE BEEN BILLED EVERY MONTH EVEN THOUGH I DIDNT RECEIVE THE SERVICE. I TRIED CALLING MTN COUNTLESS TIMES TO COMPLAIN ABOUT THAT AS I WAS PAYING TO REDUCE THE ARREARS. TODAY WHEN I CALLED MY BILL IS STILL AT THE SAME AS WHEN THEY SUSPENDED THE SERVICE AND THE OPERATOR CONFIRMED THAT HE CAN SEE THAT THEY HAVE BEEN ERRONEOUSLY BILLING ME. WHAT IS WORSE IS THAT THEY HANDED ME OVER EVEN THOUGH I HAVE BEEN PAYING. TODAY AS I WAS TALKING TO THE OPERATOR THE PHONE GOT CUT OFF WITHOUT ME GETTING A REFERENCE NUMBER AND BEEN TRYING TO CALL SINCE. THIS IS A SERIOUS PROBLEM BECAUSE IT IMPACTS MY CREDIT RECORD IN A VERY NEGATIVE WAY UNNECESARILY. I DO BELIEVE THAT IF THE RECON HAD TO BE DONE, MTN ACTUALLY OWES ME FOR OVERPAYMENT
