I just got call from a Private Number(no phone number displayed on called id) that was like the previous messages. At first it sounded like they were from PG&E and giving me a discount. But although they knew my name and address, they wanted the account number from my bill in order to get the discount. They did mention Smart One, but it was unclear what the connection with PG& E was. I asked why the caller id was a private number, and got something about the number has unlimited calls. I asked for the number for Smart One so that I could check things out. They hung up.
