Performed a search of the forums and didn't find anything so I figured I'd post this.

Had a Just Energy representative come to my door about an hour ago and told me that I "NEED" to show him my utility bills so he can confirm that I have rate protection on my bill.
I asked if he worked for my service provider and he said no, I asked him more than once why he needed to see my billing and he wouldn't answer my questions, he kept telling me that I need to show him my billing and he will wait until I do.
I was very close to physically removing him from my property when I finally told him the billing is in my wife's name and not mine; he then told me he would come back when my wife comes home and left.
This guy was insistent and would not provide me with any credentials which would require me to give him any information.
Looks like this is a scam. If you have one of these people show up at your door I would suggest that you don't give them anything and insist that they leave your property immediately.
