I believe we had 1 of those people in the apartment complex a couple months back. My downstairs neighbor called me quick & warned me that this woman was coming up & going to try to help me lower my ComEd bill. The woman comes up & right away starts talking to me, basically saying that she was in the processing of getting me set up.
I told her in no uncertain terms that she should NOT be knocking on the doors here & also, if she hooks me up with anything with out my permission I was going to sue her 6 ways from Sunday. She said sorry & practically ran down the stairs to get out of the building.
I don't really like ComEd much, but don't try to bum rush me in to any kind of sales pitches & then "hook me up" without my permission.
