I got a call a few months back on a Monday from the credit card fraud squad asking me if I'd been in France, Spain and the UK that weekend. "Mmmm, not unless I'm superman" I say, Well your cedit card has been put over it's $10000 limit with transactions in these countries. "Uh?" I say. After much talking it happens that holiday packages and hotel bookings were made using my card number and the packages would most likely be sold off at a one time low cash price in the local pub! In the end they sent out a form with all the dodgy transactions on it and I just had to sign it and send it back for a full reversal of funds. When I asked how they got my number and how can I stop this, they said it can happen any time a card is used online or even can be scaned in the dairy and sold overseas. Unfortantly no real way to stop it except to keep an eye on where you are using it.
