My brother asked me to look into this for him as it happened at the weekend and he's away on holidays since. He used an ATM at a petrol station on Saturday to withdraw 200euro. He went through the procedure as normal and at the end the machine said to take card and then to take cash - but no money came out. He just presumed there was no cash in the machine and withdrew it again somewhere else. But when he checked his online banking the first transaction is there and his account is now down 200euro. How should he go about sorting this out? How can he prove he didn't actually get the money?
