Sort of rude man, knew the name of a person who lives in this residence, but I said they weren't available to talk. I asked if he would like to leave a message and he said he'd call again. When I asked if I could say who had called he said "Firefighters" and tried to end the call. We are on the do not call list and I told him so. Since we have caller ID, I know they have called and left no message a few days ago. looks like a scam to me.
