Salesmen for solar company

got this call from "Smart Energy Center" who claimed to work as a broker to find government rebates for me because my bill was over $70/mo. Salesman was vulgar and insulting and when I asked to speak to a supervisor, another young punk came on the line and said his name was Enrique Iglesias. I told them I was on the do-not-call registry and he claimed they were exempt since they weren't selling me anything.

Used to call regularly in the past, then stopped, now started again. This is a solar energy telescammer. Add to call block list. I did.
