I received the same phone call - missed it - called back - He went through his speech about the special offer..... I gave him all of my information (reason being- my roommate is moving out and I will be switching our PG&E account to my name)
After he hung up, I quickly looked for a thread like this one. Once I figured that it was a scam call, I called them back.. 15 times.. I called back and never said anything. They juggled my call from one representative to the next and then finally sent me to voicemail. I left a beautiful message full of pressing buttons to make music! I will be calling back non-stop for the next few days. It's just what they get for hanging up on me the first time. ;-)
