Same happened to my gf - got transactions indicating saswitch on her bank statements. 2 x withdrawals of R1000 in Pretoria. She called and card was stopped. She got fully refunded in the end. We analysed her bank statements, thinking where she could have had her card skimmed, but she barely used it that passed week.
I did however read up on their Absa's policy, where they say that if you were negligent with your pin then the won't pay. If not, then you get refunded. At least, that was the hint. Now, pretty sure nobody peeked my gf's pin, but they were somehow able to withdraw.
I am suspecting internal fraud at the bank or perhaps there is a way to determine the pin of a skimmed card. My bet is that you can talk to someone at absa and they will provide you with a card and pin.
