Got a call from this number on a phone which is on the federal do-not-call list. They didn't respond immediately, but after a few seconds a rep came on the line and stated he was calling for some energy company (unfortunately I forget the name). I didn't wait for the pitch.
Caller knew my first name, but rarely do I receive calls from anyone but family on my home number. He called me a lying b*tch when I said I didn't know who he was. Very strange call. I ended up Hanging up on him.
