Who called from 6476940203

Received a call from this number, but they didn't leave a message.  Caller ID showed V63019391700012.  Looks like a spoofed number/scam.

Green Energy scam.  Told him I couldn't talk, I was waiting on a call about my ducts.

called for home owner.  scam.

Received a call from this number where a male figure claimed he was with some energy company. He asked for the home owner who wasn't available, and once I asked if I could take a message he hung up... seems like the "yes" scam to me

See Mike's post above. The "yes" scam is just a rumor. A widely publicized rumor, yes, but just a rumor all the same.
