This number calls to notify you about stolen credit card or such... it's a SCAM! Person calling uses VoIP and can't be traced, but if you're familiar with Wireshark, then you can digest the persons IP and details. Be careful!
I answered because I know people in 607 and I thought it might be pertaining to something of importance. Some bullspit about a final warning about "your credit card". When they don't come right out and say the name of the bank you know it's a scam. Calling back goes to a dead end. Again, if it was legit, it wouldn't.
