not so worry, last time my hubby withdrawed HKD3000 and thinking of other thing, go away and with a short while he recalled and no more money. Called the bank with all the details, exact time, location, bank replied investigation and later a letter rec'd the ATM machine has detected the money has not taken and the machine absorb the money, money will then deposit back to his account.
hey, like my hubby said, who will be stupid enough to take those money as there is Close Circuit TV tapping the image, unless the guy took the money and went away, or else, once he inserted his ATM card will record his face image and the account number.
