Just got a recording call from the same number claiming to be from "My bank's" fraud department checking on suspicious activity on my account. They had my name correct but not the last 4 digits of my CC. "Press 1 if you are this person, press 2 if they can not come to the phone.. At this point I hung up. The caller ID just listed it as "Toll Free" with the number. I called my banks real phone number and they searched their data base and said it's not one of their phone numbers. I had them forward what happened and the number to their fraud dept.

It's chase banks customer service

It was a call from Chase bank confirming a change on account information to make sure recent changes weren't fraudulent.
