Appalled by Mtn- very disgruntled customer

Good day,<br> <br> To whom it may concern.<br> <br> <br> After several correspondence with MTN, I am at my wits end. I've had enough...to put it bluntly (I'm gatvol). To date, this matter has neither been resolved or have, I received any feedback from MTN. The only feeble response, I received was to (settle the account.)Not knowing what, I am being billed for. Reasons need to be given to me, as to why my account seemed to go up suddenly. This has been going on for far too long. <br> <br> As, I have previously stated in various emails and calls, I have made to MTN, soon after taking my phone in for repairs at your service centre in Montague Gardens that my account NO: *** INCREASED DRAMACTICALLY! Could this perhaps be a case of my celluar phone being cloned? Because, what do I know about data? Let alone the internet. These are the questions,<br> I need answers to. Immediately, after noticing the difference in fees , I went to the MTN store in Century City and spoke with Asha Ref no: *** and was advised to send my query to the billing department to investigate. And was given absolutely no feedback- how pathetic! <br> <br> This has been on-going since last year March-April
