They never leave a message, but I finally answered - it was a solar sales guy (American Solar?) trying to sound like he was providing me with a PG&E notification on my energy bill.
This number has called my home and my cell multiple times. All I know is that it's coming from Hayward and it's a landline. They do not leave a message.
I also received a call this morning at about 8:30 am on a Saturday. I called the number back on a restricted number. A recording came up on their end saying it is some solar company. I have heard the same recording (and voice) from a difference number.
They call everyday and leave no message. I finally answered and it's some guy named Akrabah looking for the adult in the house. Acted like a kid and they hung up fast.
