5/24/16 12:06 PDT  Another idiot can't take no answer, just keeps trying even though they are blocked.

The Caller ID came from this number but it was a robotic voice claiming to be from the IRS (Not "Internal Revenue Service) and that they have filed suit against me.  Uh huh.  Sure, Jan.  The number they left as a callback number is 270-945-9668.  Yeah, I'm not calling them back.

Got this call from "Name Not Found" and blocked it. They immediately called back and as all calls from Out of Area (without number listed) are also blocked on our phone, they just wasted their time.

Caller ID field was totally blank. No message left. Number now blocked.
