After showing up at our office claiming to be able to give us solar energy for free AND cut our electric bill in half, he called nearly every business day trying to pressure us into it; when we weren't interested, he showed up again at our office about two weeks later and got mad and was insulting when we said we were not interested. The individual's name was Sammy George. Hang up or run if he contacts you. Be aware that he uses multiple phone numbers from the same area code to make calls.
