Did not answer.  No message left.
CID:  Unknown Name

salesman was threatening and would not accept my demand to not call my number again. He said he was calling from solar solutions.

Same as s eslick above. Spoke to this  person. Told him I'm not interested, to not call again. He spoke unintelligible language, which I assume was filthy and hung up on me. I have this number blocked now.  

Keeps calling and not leaving a message when we answer it takes a long time for somebody to answer so we hang up.  Last night somebody actually came on the line (guess I waited long enough). I advised her we are on the do not call registry,  and she started off saying she wasn't selling anything and she would call back the next day at 7 in the morning when I would be more cooperative.  Then hung up.  I told her not to call back and I would be reporting the number, but I'm not sure how much got through before she hung up.  I called the number back that came through on my caller I.D. But it said the call could not be connected and call back later.  I called back with the same result.  I called solar solutions in Bakersfield they said they do solar screens and the business may be solar city.  

Our outgoing message states that we screen all our calls, so to identify oneself, etc.

This coward hung up after the tone.
