Who called from 2012974336

i am constantly getting this number on caller id as a unknown caller. irritating as hell.

There is no name given, but the number calls often.  
On this site several different names are given.  ron, Spiffy, noneyourfvckin business, S. lopez, Billy and
San Francisco Bay Area Resident.

Must be VanRu credit collection agency. Got student loan debt?

Caller ID came up with "Out of Area" so I didn't answer. The caller didn't leave a message.

That's the phone number of a van ru credit corporation representative.
