They just blocked you without sending a fraud alert asking you to confirm the purchase? Dang.My CC company blocked me at the gas station the other day, for fraud alert. I had just filled up my tank and was taking my wife's car in to fill it up. Apparently two charges at 7-11, within 10 minutes, is enough to trigger it. I had to go home and get her card and come back, to get the gas. I've had my card compromised before, but not in a while. Last time was charges at a office depot in Florida.
