TELKOM won't pay me back money that it owes me

On the 20th of December I paid my December invoice by paying at Pep. This was after a call centre agent told me that if I paid the invoice amount, my bank account would not be debited come the end of the month.

On the 29th of December Telkom debited my account with the invoice amount. Effectively I paid twice for 1 invoice.

When the debit order occurred I called Telkom for them to do a reversal of the transaction. I was told that the reversal would be done within 72 hours. Those 72 hours lapsed and I had not received my money back from Telkom. When I called the call centre I was told that a supervisor would call me with regards the matter. That was last week Wednesday (3December) and every time I've called since then I've been receiving the same useless line from call centre agents that I will be contacted.

I called again today and I was told that my matter was in the wrong She, whatever that means... I requested to speak to a supervisor and the agent I was speaking to dropped my call.

I WANT MY MONEY BACK FROM TELKOM... I'm really frustrated by your actions and fail to understand why YOUR MISTAKE should be my problem.!!!!
