I paid my DSTV subscription but DSTV went and disconnected my services ( Poor poor Service)

I paid my DSTV account on the 30th of May 2018 of an amount of R450.00 via EFT and today they disconnect my service. When I call them they tell me that there has been a reversal in my account but the reversal was not into my account but to some account ( ********** 4) and they do not know who the account belongs to. This is a bad service and how do you protect your customers if you will just allow anyone to make reversals from your customers’ accounts, surely there was no verification done here. I was on the phone for more than 30 minutes with a DSTV consultant who couldn't help me or tell where the reversed money went to.
