Pay back the money - MTN

<p>I have dealing with MTN as a loyal customer for the last 8 years..and every month I have paid my account from a debit order..but NOW 4 months ago I owe them over 16 000 RAND !!!! I query it with them and the support staff from MTN old mutual says they will log a call but my account will be suspended until then. I could not have this as my wife was overseas travelling on business.so i paid the overdure amount in retrospect of a query being logged to sort the amount out..ONCE THE JOKERS LOGGED A CALL..THEY SAY THEIR SYSTEMS DO NOT GO FAR BACK AS WHEN MY ACCOUNT STARTED AND CANNOT TELL WHY MY ACCOUNT STARTED WITH A BALANCE OF 16000. please.......if you cannot tell me where the amount is coming from..then you sure as hell cannot charge me for it...and I want my money refunded immediately as this query has been dragging on from September. ALSO PLEASE GET YOUR JOKERS FROM THE MTN STORE IN OLD MUTUAL SOME TRAINING OR DECENT COMPUTERS AS I HAVE BEEN THERE OVER 10 TIMES AND THEIR SYSTEMS IS EITHER SLOW OR DOWN AND THEY HOP FROM ONE COMPUTER TO ANOTHER TO SORT IT OUT...</p> <p> </p> <p>I AM ABSOLUTELY FUSTRATED THAT AS A LOYAL MTN CUSTOMER I GET SO BADLY TREATED!! </p>
