I hung up when I received this call, asking for payment. I looked up Portland General Electric's phone number on the web (not the number that the scam call gives you to call) and contacted PGE. They warned me of a scam call going around and said PGE would never demand payment over the phone. So, there you have it.
Thanks for saying what I wanted to say to him. I'm so done with these people who judge others, especially people they don't know and without knowing anything else about the situation.
