We got a call from that number today also. Said it was the electric company making an appointment to come check out our house to see where we could save money on our electric bill. You cannot call the number back, as the computer voice says it is not in the database. Probably a scam to get into your house.
I have had this number call more than once, saying they need to speak to the owner about the Electric Bill, when i asked them what company they worked for they just kept repeating "Are you the owner"? They were very rude. I asked if they were from our local electrical company and the person said "Oh My God, how many times are you going to ask that, I'll call back when you're in a better mood" and hung up on me. I tried to call them back but it won't let you.
