Called left no message on private business line.

Caller left no message upon call back to see who called me. The automated message claims to be some GMC credit services. I have nothing neither financed nor any outstanding debt so these clowns must be trying to up sell solicit or defraud somebody.  - MY BUSINESS RULES ARE DON'T CALL ME - IF I WANT OR NEED A SERVICE II'LL CALL YOU !!!
