Credit card fraud departments are generally good about this.
I said wait a minute, you called me. Shouldn't I be verifying who you are?
The guy kind of laughed and said yeah, but this is the process I've been given to follow. I said I would call back on public customer service number and he said that would be fine.
It turned out it was a legit call, but just weird that they would operate that way.
I wish I could remember who it was. A credit card, I think.
I told her that I preferred to call the AT&T number and for her to tell me what options should I press to get to her. She couldn't give me an answer to that.
Most likely a scam I guess.
