got a call at 1:20pm on 1/29/2016. said hello; no response, then they hung up

Got a call from 818-797-4094 but did not answer.  Called it back and got an answer machine that wanted to know if I wanted solar to leave my number.

They've called me at least four times now, and every time I do not pick up. They never leave a message.

Called me once on 3/16/16, just one ring. I didn't pick up and they left no message. I've gotten many calls to similar phone numbers to this number that seem to all be "solar" related.

Keep calling calls from them even though I ask to be removed from their call list. The last person I spoke to refused and kept badgering me rudely about reducing energy costs. I finally had to hang up on them.
