Interesting that the bank accepted that call, from a withheld number.
I think I approve. It suggests to me that particular bank might understand that caller id can be spoofed, especially by the bad guys, and so it contributes nothing to security.
Not long ago, I mistakenly suspected fraudulent activity on a card. I called the bank in a bit of a panic, wanting them to cancel the card. In my panic, I seemingly answered one of the “security questions” wrongly, as a result of which they refused to discuss my concerns, or to cancel the card. Instead, they just politely ended the call. Good job my suspicions of fraud were mistaken, but can’t help thinking their security process left something to be desired.
