The same happened to me just before Xmas at the ATM at the Co-op on Forest Hill Road. I didn't cancel the card until the next morning by which time a few thousand pounds had beentaken from my account in 19 chip and pin transactions. The bank haven't paid me any money back yet as they were chip and pin. The lesson is if the machine keeps your card, cancel it immediately. It seems like this is happening a lot in our area
