Beware of credit card cloning

Hired a car at Cape Town Airport. Swiped two credit cards as first one didn't have enough credit. Within 2 hours, *****ulent transactions were attempted on both cards totalling over R170k. Fortunately most but not all of the transactions were picked up by my banks' ***** divisions. Still considerably out of pocket. Two other credit cards in my possession were not swiped and were not affected so almost certain that the first two cards were copied or cloned by Woodford personnel.
