Re: This is this bank
I refuse to confirm my details with them when they call me unexpectedly
I once had a cold-caller from the bank get very aggressive with me on the phone when I wouldn't confirm my identity. She didn't seem to understand that I'd never heard from her before, didn't know her and (since her number was withheld) no way of validating who she was so why should I give her my private information?
I suspect that she was on a quota and I was messing her completion rate. And my level of caringness and sympathy was somewhat adjacent to zero.
