Who called from 4046092411

This is a credit one bank number. They are a credit card company.

Several complaints here - http://www.whitepages.com/phone/1-404-609-2411 - claiming it's a scam.

Yes really. I have a credit card with them. I answered the phone and it was credit one bank. They've also left messages on my phone before.

...doesn't mean it was legitimate.  Scammers are known to spoof legitimate numbers!
