KFC skimmed my card

I bought a takeaway from KFC Walker Drive Port Elizabeth on sunday 18/2. I usually tap my card to pay but on this occasion the window cashier asked me to insert my card which I did. He then took the machine and dropped it behind the counter so I could not see what he did. He obviously skimmed my card (on no other occasion has the card left my sight). Later in the evening I got a request from my bank to authorise a payment for about R2,800 which I rejected as I did not make this payment. I checked my bank account and found a payment of R86 which I also did not make. I immediately cancelled my card with the bank so my maximum loss is the R86. I then completed the KFC on line complaint form. What annoys me is that after 1 week I have not received a response. I assume that whoever reads the complaint is either too lazy to actually do anything, or KFC are happy to employ ******* as cashiers.
