Who called from 5309619088

Just got a call from them.  I didn't know who it was so I didn't answer and they didn't even wait for the answering machine to pick up before they hung up.

Number calls - no one is there. I call it back after 30 second it says your call will be transferred to the next agent and then hangs up on you.

Just got a call from it.  Empty line, no one there.  Probably robo dialer checking for active lines.

Just got a call and hung up ,recive 3-4 calls a week from this number

Received another call from this number on 8/6/13.  No message left, didn't answer.  It probably is a robo caller checking for active lines because four hours later a call came in from 360-322-6158...a number know to this site as a "dangerous scam".
