The person knew my name and address. They asked me if my electric bill was over $70 a month, which it is. They then said I qualified for a free inspection of my roof. If my roof was suitable, they would put solar panels on it. I declined the "free roof inspection". The guy became upset with and and asked me why I'd turn down something that's free. I told him because I can. Then he acted like I was stupid and hung up on me.
