I ran into that with a credit card company recently. They called and left a message about suspicious activity on an account and a callback number. I couldn't find that number anywhere on their website or the web in general. I ended up calling the main # and connecting to the security department. It was a legitimate message they left. I mentioned the phone number thing and they agreed that was an issue but who knows if they acted on it.

The number isn't published because it's outsourced, your bank is not the one handling the call. The agents will speak as if they're from your card issuer, but you will notice all the automated systems will say "cardmember services" or other ambiguous name.

"Cardmember services" is also a notorious phone scam.

I got called about suspicious activity on my card and the woman asked for the last 4 of my SSN to verify my identity. I asked "how do I verify your identity" and she told me to hang up and call the phone number printed on my credit card.
