Received multiple calls from this number. Decided to answer it today and it is a company called RPM Collections. The number shows up as a Virginia number but the lady says they are in Washington. Apparently I have/had a old Nextel account that is in collections from 2005 for $73. I told them I was on deployment at that time and swore I resolved it in Feb.2006 and to have Sprint/Nextel call me.
I've received a few calls from them over the last couple of days. I just called back and it was indeed RPM. They were searching for indvidual with my same name. I'm not sure how they got my number (perhaps they searched some database and were trying to track down this guy. I verified that I was not the indivudal who they were looking for and they assured me that they would remove my name from their call list.
