got a call from 408-816-9733, though i didn't answer and they left no message. I did call the number back and a recorded voice said "s.r. green energy solutions, all our agents are busy, blah blah blah."...their "mailbox" was full so i couldn't leave a nasty message for them, about how i was on the do-not-call list, and to not call me (rats!).
This number showed up in Caller ID. They did not leave a message, making them "suspect." We call-screen. No recognize caller, no talkee. Put them on call-blockade. Message to them: "Up yours."
