i've gotten unsolicited calls like this before from my insurance company and when i tell them i don't provide personal information to people who just call me out of the blue and ask for it, they act like i'm from mars.
then of course i have to call them back, sit on hold (and maybe get the same call center agent!) to verify their identity and conduct whatever business they originally called about. thanks, your bad practice just cost me an afternoon to deal with the inefficiencies of a private industry i think shouldn't even exist.
“Hello this is your bank can I please confirm your personal details?”
