Sorry to hear this, hope it gets resolved easily enough, with minimal hassle.
I had my CC # stolen, I THINK from Tiger Direct. I always used PayPal with them, and one time I used my card. Next thing I know, I get a call from the CC company (they have been quite good to me), with two charges to Tiger Direct. They instantly credited me, and I also called Tiger Direct; they stupidly gave me the ship-to address (from what i learned later, they're not supposed to do that), and I told them they may want to hold/return/cancel the shipment. The sad part is, even with an address, I called my local police and the police in the CA jurisdiction, and no one seemed to want to do anything.....too much of a hassle.....
