Who called from 4084759271

Nobody was on the other line for a little while, but after a long pause, a robot named "Greg" started talking and I hung up on him.

Same as above. Pause on the line and a guy named "Greg" said hello. I asked him can I help you? and he hung up. Caller ID says "Sunnyvale, CA"

Absolute spam.

"Jason" has called me many times.  Says he will remove my number from their call list, but never does.  I have told "Jason" in the past what an a**h**e he is but he keeps calling back.  Today he called me 2 minutes right after he said again that he would remove my number.  I didn't answer the 2nd time.
