We just come back from our trip to London and Paris. We had no problem getting cash from ATM (only used once) in London. When my husband tried to get some Euro from the Eurostar station in London before heading Paris, with no warning whatsoever, the machine just took his card as if nothing happend. No invalid card message. Then I tried my card at Societe Generale in Paris near the hotel, it seemed to work as it asked for pin and amount, while I was waiting for my card to be retured and the cash would come afterwards, the machines did nothing and eventually said the machine is not available anymore. It kept my card. Later a receipt came out said I withdrew the money. I did verify with Citibank that the transaction was reversed and till this day they don't know why both of our cards did not work and yes, we notified them of our trip in advance. When I got my card back from the bank and tried one more time at their machine, it won't even accept my card, but I have no problem using it to make purchases. Can anyone shed some light?
