Who called from 2815378409

Just received a call from them this evening. I promptly filed a complaint with the National Do Not Call database, so hopefully they will be investigated.

I received a call from the number, it just hung up.  
Are they scanning for modems like they did in Wargames? (a movie)

I got a call from this number this morning.  When I answered, they hung up.  It's a waste of a minute on my pre-paid phone!!!

Just got this call! Then they hung up! WTF!!

I got a call from this number on 9-22 @ 6:51pm.  Didn't answer as was unsure of who it was.  No voicemal and no return calls.
