Got a call from this number.    This number belongs to GMC Credit Services aka Glass Mountain Capital.   They are calling for someone that does not live here.  

Had the same trouble with several credit agencies last year looking for the same guy.   Wrote about 20 cease and desist letters before the callers stopped and now they are starting up again.  

They're people are seriously overpaid if all they do is pull numbers out of a hat and harrass innocent people.
