Telemarketer. There IS a way to block future calls from this and every phone number you don't want to have call you. I set up a contact named AD - BLOCK THIS. I add every scam number to this. Have 13 numbers now and growing. On my iPhone, i blocked the call by going to SETTINGS --> PHONE --> BLOCKED and adding the contact name of AD - BLOCK THIS (or whatever you want to call it). I no longer get calls from each of those designated numbers.
Called yesterday around 4pm, then today around 5pm. No msg. Most likely old/disconnected number being faked as current. Shows on caller ID as Shawn Carney (or Carney Shawn). Blocked.
Claim to be representing PG&E in some sort of renewable energy thing. Have repeatedly asked them to stop calling - finally reported them to Do Not Call registry.
