Caller id displayed Ramona CA. Caller spoke w/ accent and claimed to be calling from "Greenworld Pro", (although, call sounded like it could have originated from overseas). Caller asked (he was reading a script) me if my energy bill was too high and perhaps I could qualify for gov't programs to reduce energy bill. I told him I had solar and caller terminated call. :) Lots of boiler room noise in background. I've been receiving lots of these calls lately and sales pitch is exactly the same! Beware!
