Caller id displayed Lucerne Valley, CA. Caller identified himself as "Francis", had thick foreign accent, was polite, said that his records indicated my energy bill was above $70/month, and I could get energy upgrades that would reduce my bill. I informed Francis that I was a renter, and he seemed disappointed and politely ended call. I'm certain this is one of those solar telemarketers. Called me on a Sunday morning. Also received a call on Saturday, exactly the same time from Lucerne Valley, CA from this number: 760 248 8861. I did not answer that call, but I'm certain same company. (Lots of loud, heavy boiler room noise in background during call.)
Another fake phone number and spoofed CID from long time scumbag boiler room solar telemarketers. Block the number, they can't scam you if they can't reach you.
