I get automated calls asking to confirm purchases. Just to make sure I don't slip up someday in the future when something fraudulent calls, I always hang up on the bank that called me and call them to confirm my purchases. It's only a slight hassle to make the call myself but I hope it keeps my auto pilot under control in the future.
I have to point out that when my bank actually calls me, the caller id never clearly states it's my bank (and I have more than one). I know caller id can be faked but c'mon! say who you are already.
Hope everything works out for the OP.
