DSTV can not allocate payments

I paid my DSTV on 5 January with a card, yet today on 10 January I receive a message from DSTV informing me that I have to pay a different amount as my DSTV has been suspended. I phone DSTV and am informed by a rather rude lady that the payment bounced. I inform her that a card payment can not bounce and that the money did not come back into my bank account upon which she tells me it is the bank's problem. I then phone FNB and am informed that the payment was made successfully and that it has not been returned. I paid the amount due to have the DSTV reconnected, but can not seem to get an answer with regards to the initial payment made. Not a happy customer.
