SFE Energy door to door misrepresentation Annapolis Maryland

Door to door salesman came to my house today and pretended to be from Baltimore Gas & Electric company, said they were there to confirm my electric rate plan and keep my rates low for the coming year. He conspicuously waved a clipboard with a printed out BGE invoice on it, but had a tag around his neck that said SFE. When I questioned him further, it finally came out that he was, of course, selling electric rate plans, was not with Baltimore Gas & Electric, and etc. 

I don't understand why these people lie about things to try to sell their product, I guess maybe it works often enough to make it worth it for them. I told him he had misrepresented himself and closed the door.
