Automated voice that said 'This is about your electric bill'. I didn't wait for more, just hung up. I don't think my electric company would be calling from California when I am in NY!
Received a call from this number stating this was the final attempt at communication, they were going to be installing electric meters at my property, and I could expect a 16% increase in the bill. It said to push 1 for information on how to prevent this. I accidentally pushed zero/
I received this call with the recorded message stating "this is our third and final attempt to contact you" and something about our gas & electric meter being changed. I pressed one, heard music for a minute, then got disconnected. I think this was some type of spam since the source in in northern CA and I live in southern CA, and my power company would be local. Also, my meter was already upgraded this year.
