Just like some scammer will call saying they’re from your bank wanting verify information. They want you to tell them your personal stuff. Of the several times I had a call I simply told them, well you supposedly have it in front of you so read it back to me. Same with those IRS scams. On the bank calls I just tell them I’ll call back using the number on my card. They hang up. “Unknown Caller” showing up on your phone caller ID clues you in right there.
I called the bank's number once about some issue with an account, and the person there really screwed up.
She asked for my account number.
Now, I don't remember exactly what this was about, IIRC it was some screw up by the bank and I was ticked to start with.
Anyways, when she asked for my account number, I came down on her hard. I I said, *Oh no! When we opened our account with the bank, they told me that they would never ask us for our account number.*
Boy did she backpedal quickly.
