I had a recent card that HAD NEVER BEEN USED. I activated it and kept it in my safe.
Got a nasty-gram from the cc company said I was 3 months late on some charges.
On july 8th someone in Indianapolis filled up two gas tanks and made a $100 cash advance.
I was in Seattle that day. Again, that card was never used and was in my gun safe at the house.
Inside job with cc company all I could think of.
You didn't end up being liable for any of the charges were you? I have never been hacked (knock on wood) but have been scammed on internet purchases to which my bank took a claim and refunded all my money.
