I keep getting calls from San Francisco Peninsula. No one answers usually but I've had a couple of calls asking for other names. I think they just fish for info. I think it's a solar company. If I call back, I get a recording that it's disconnected. I tried to block the calls on my phone but "they" are somehow using phony numbers.
