Per my mother in law, the CC company said for her not to use her card. Can't say it was correct info or not; only what she told me.
Understood. I've always had them block just the associated card.
My favorite "fraud alert" credit card story? About 10 years ago, I had about a two week trip where I had been to Romania, Ukraine, Dubai, Afghanistan and Pakistan.... no problems whatsoever with my AMEX in any of those place (no credit cards for anything back then in Afghanistan). So, I get home and that night had to buy a new fridge online from Lowe's. Declined. Re-ran with Chase rewards card, no problem. AMEX texts me with suspected fraud alert. I called AMEX and ran through the transactions for the last two weeks and said, "But with all THOSE countries, the transaction you stopped was a fridge from Lowe's?!?!?!" They said, "Well, yeah, we know you go to those places, we didn't know about Lowe's."
PS wouldn't trade my Delta AMEX card for anything for piling up Delta skymiles and the other perks that come with it. The Chase card we have is great too... piles up rewards points that are straight up cash when booking flights/hotels. We also put everything on credit cards for rewards and then pay off. I even buy aviation spare parts on reward cards! ;)
