Just had the same experience. Some f*** face got my card details and spend USD 2000 on some casino / poker site.
The card details was not lost on the internet, it was in a shop/reataurant or whatever they tricked me.....
I contacted my bank and told that i didnt authorise these transactions, two days later i had the money back.....
The bank and some other authority is now investigating the fraud. I only have to pay the amount back, if i gave wrong information (spend the money myself).
Its a b**** to get new card, new PIN etc.....damn.......
