Bank of America decided I really had been in rural France buying tires when I had proof I was at work, at my desk, in Boston at the times of the purchases, and the card was in my hand. It's been 20 years and I still won't ever do business with them again.
It was much more fun, at least, when Amazon tried to tell me one of my children must have taken my card and made the purchases. I took it to mean the children I have not conceived yet will have access to time travel, in which case I'm not even mad. Pranking me in the past deserves whatever trinket they bought!
