These door-to-door energy salesmen came by my house wanting me to switch energy companies.
They made several worse-than-dubious claims including trying to hide the fact they were representing another energy company rather than the one I had.
In any case they wanted to offer me $29.95 flat rate for unlimited gas usage. They claimed thirty day money back guarantee, at which point I told them to leave. (Scam has now become obvious--it would take four or five months to notice if they were lying and the money back guarantee is shorter than that).
I'm convinced they took in a lot of my neighbors.
They actually wrote their offer rate onto the piece of paper they wanted me to sign without reading. Let us say I hadn't told them to leave, how long would have the company actually selling gas had to honor that ridiculous rate?
Hint: the rate is ridiculous because I would gladly buy a natural gas generator and switch all my electrical stuff to gas if it were remotely competitive because PG&E can't offer reasonable power availability guarantees anymore.
