Pay Point reversal never took place

Hi

I have been trying for the past week to resolve a reversal on my Credit Card that never took place. Been on the phone with FNB customer service's, FNB Reversals, FNB Credit Card services every day and nobody in the whole of FNB can solve my problem that's clearly an FNB issue. So in short my problem is the following: a payment was made at a hotel for a booking via a speed point and that transaction was reversed (have a copy of the reversal printout from the speed point), but after 4 days the reversal did not show up on my account and still doesn't. Looking into my transaction information on the FNB site, the transaction is not even shown there, but after speaking to a consultant he send me the transaction records and it's shown on those, now when I call FNB Credit Card services they also cannot find the transaction, so nobody seems to be able to pay back my money that was reversed, my account does not reflect any reversal, so that money is now lost????

So what should I do, paid the vendor twice due to a reversal that was supposedly to take place but never happened.

As it is, FNB responded with a message that it will be sorted by the relevant department, but as it is I have not heard anything from them.. wonderful
