My entire card details got stolen recently, including my name, address and phone number. The first I knew of it was when an email came in with a verification code for a multi-thousand £ purchase for a hotel reservation. I was just thinking it's an odd looking phish when my phone rang. I ignored it as I always do and then it immediately rang again, so I answered it:

Them: Hello, is this Mr Zanzibar?

Me: Yes

Them: This is Amex fraud dept. We've noticed some odd activity on your card, did you make a purchase at x for y in the last few minutes?

Me: No.

Them: OK, great. It's been flagged and declined on our end so your money's safe. Just so that I can get this closed off, can you confirm the code that was sent to you?

Me: ......Nnnnnooooooooo?

Them: immediately hangs up

Obviously then had to then call the real fraud dept and cancel my card, but I was annoyed by how little of a shit they seemed to give. No curiosity of where they could've got every detail of my card, no advice of what to do next, just cancelled the card and issued a new one. Thank you, next caller please.

Spent the rest of the day both relieved that I didn't fall for it but also furious at myself because the best response I could come up with in the moment was "no". I could've at least told them to get fucked!
