they call and they want you to give them all but the first four digits of your credit card # and they want the expiration date. They say they can lower your interest rate. This is a scam I feel and will never provide this information over the phone. I wouldn't recommend falling for this scam.
Missed call from this number. from Duncan, Oklahoma. the phone seems to have been used by "Rainman Roofing & Construction, Inc." at some point. Damn I'm bored.
