MTN BILLING CLIENT UNFAIRLY

I OPENED AN ACCOUNT ON THE 29/07/2015 WITH THE HELP OF ELIZE BEYLEVELD ERMELO MTN. THE ACCOUNT IS A 24 MTH MY MTN CHOICE 1GB@R79 ELIZE ASSURED ME THAT THE ACCOUNT IS A TOP UP ACCOUNT SO THAT I WILL NOT BE BILLED MORE THAT R79 I CAN TOP UP MY ACCOUNT WHEN DESIRED WITH A PEACEFUL MIND I ACCEPTED. I WAS THEN BILLED THE 01/09/'15 R1673.12 AND WAS INFORMED THAT MY LIMIT WAS NEVER SET AS A TOP UP ACCOUNT I THEN CALLED 808 AND THEY SET MY LIMIT AND ALSO INFORMED ME THAT ELIZE WAS SUPPOSED TO INFORM ME TO CALL IMMEDIATELY AND SET UP A LIMIT ON MY ACCOUNT. I CONTACTED THE STORE MANAGER ELIZE SHE GAVE ME A REF OF HER USB TO MTN REF***. I ASKED THE ACCOUNTS DEPARTMENT TO CANCEL THE ABOVE MENTIONED AMOUNT SO THAT I CAN PAY THE AMOUNT THAT I SIGNED UP TO PAY. I AM UNWILLING TO PAY THIS DUE TO IT NOT BEING MY FAULT. THERE IS STILL NO HELP FROM MTN'S SIDE THEY SAY THAT I MUST GO SEE THE STORE MANAGER AND SHE SAYS I SHOULD CALL 808. I AM VERY UPSET WITH MTN'S SERVICE AND THE INCOMPETENCE TO ASSIST THE CLIENTS.<br> I WOULD APPRECIATE IT IF HELLO PETER COULD ASSIST ME WITH THIS CASE,<br> HERE IS MY PARTICULARS AS ALSO THE REF NRS.<br> J VAN DER WALT ***. REF***, ***<br>
