Who called from 8646079324

Some one called from this number...No answer, No msg..When I called back no reponse...

Got phone number from 864-607-9324, said South Carolina on caller id. I got the call while I was out, and since I'm currently job hunting, I returned the call in hopes it was a prospective employer. No answer or machine, just rang and rang. After seeing this, I'm very suspicious about the whole thing.
