Multichoice not refunding double payment

On 7 July 2015 my Multichoice debit order didn't go through, because of insufficient funds in my account.<br> My fault - thought all debit orders have gone through by that time of the month.<br> <br> I was under the impression that Multichoice would make a double deduction the next month, but was then messaged on several occasions to make the payment ASAP.<br> <br> I was even phoned by Multichoice to ask if I had made the payment, which I confirmed I did on the 17th of July - via EFT into an existing ABSA Multichoice account.<br> I asked the gentleman to phone me back if he could not trace the payment.<br> <br> Received no call back in the coming weeks, so all settled I thought.<br> <br> Alas no, the next month the double debit order deduction did indeed take place!<br> <br> Contacted Multichoice per e-mail and explained the situation - I even included a copy of my ABSA account statement which showed the payment, as well as the account number I paid into.<br> <br> Everytime Multichoice came back and said they could not find the payment on their database (!) and can I please make use of debit orders next time? (!!!)<br> <br> I was then ensured a higher department would sort out the problem - problem still not solved, not even communication.
