Who called from 7207353941

A recorded message about saving money on my electric bill, I hung up before the message finished.  My guess is they wanted to sell solar panels.

I didn't pick up, and no message was left. I called the number back and pressed "9" to be added to their "Do Not Call" list.

Scam, no mesage

No message left.  Don't know the number.  Likely a scam.
