No response to request for re-payment of a **** on my MTN account.

On the 14th of August last year, two new accounts was registered on my contract, for a total of R8 974,22. In the next billing period another account was added for R4 550,48. I only discovered this when I checked my bank account early in September. On contacting the local branch the assistant helped me to remove the accounts and suggested I reverse the Debit Order at the end of September. However the amount was larger than allowed for reversal. During October two data/voice accounts was added to my contract for telephone numbers *** and ***) for a monthly total of R550,50. At the time the agent requested that I provide An affidavit to explain the situation. This was done and I also opened a ***** case with the police in Table view. On receipt of the information the agent was going to ensure that I get refunded. Noting happened and by the 22nd of December I escalated the ***** with the ***** contact agents. I was promised a response of 20 working days. When I contacted them on 12 February, after no response, I was again promised action with the ref code of *** I followed up on the 1st of march (Ref no. ***) and was again promised action. I would love to see a response from MTN as the ***** amount now sit at a total of more than R15 000 and all I have so far is promises. As a very low income pensioner I cannot afford this.
