I'm sure it is very unnerving Muskrat. Sorry that happened to you, but good thing it was a credit card, not debit card. If the fraud department caught it, you shouldn't even have to dispute the charge. It's their responsibility to take care of that for you. A couple of years ago, my primary bank notified me of fraudulent activity. They are really on the ball. The charge wasn't even for that much.
Years ago, I had a Bank of America credit card. Somehow my number was used, first for a $10 charge at a gas station in Pennsylvania, then to try to buy airline tickets with a Caribbean airline, after which BOA caught it and notified me. Of course the card was canceled. My son is "co" on my credit cards. Every now and then the bank will reject a charge he's trying to make. He'll call me and at the same time I get a text from the bank. I just click that I recognize the charge. I never had to start a dispute in either of those cases.
