These people are scam artist. They were featured on eyewitness news for conning elderly people here is the link. They are all american chimney. Their address is 168 central avenue located in farmingdale ny 11735.
I have caller ID and never pick up if I don't recognize the number. If it is important they will leave a message. This number came up several times so I looked it up. I'm so glad there are sites like this!!
