I called "verified by visa" and they asked for my zip code, and first and last name before I asked for the number of my bank. They gave me the right number, but I refused to give them any information. I'll call my bank tomorrow.
This is a valid service. After verifying my personal information the automated message read off the five most recent transactions on my checking account, the most recent being a large amount. I'm glad this transaction alerted my service provider. It shows they're paying attention.
It was really the golden 1 fraud department. I made an in app purchase and my home phone immediately rang and I got the recording. At first I thought it was a phishing scam so I called golden 1 and gave them the info along with the telephone number (800) 624-7486. The lady verified that it was golden 1 attempting to verify my in app purchase on my account and because I hadn't completed the process my account was frozen. (They should only ask for your zip code and last 4 of your social.) Eventually they sent a secured message to their fraud department and unfroze my account.
