I just got a call from the Attleboro number about 10 minutes ago! Didn't answer it, but looked online and it took me here. Also, last week a guy called from the last number you list from Franklin, MA. He was a chimney sweep like someone else said. I told him I would get back to him. I thought the deal was too good to be true.
Same thing but it was a guy who called. I asked what company he was from then he asked me what type of heat I have. Then I asked what company he was from and he hung up. This is very suspicious.
