i wish i knew who it was .. i called it back and was told the number is out of order .. it was like 10 minutes between calls .. wtf???

Called and claimed they had cleaned my chimney in 2010 and wanted to do it again. I have not had my chimney cleaned in the 7 years we've lived here. Scam i bet.

I have been getting them too. Called back. Number not in service message.

These people are calling for unknown reason because when you pick up they hang up.

I feigned interest and asked for a number where I could reach them after getting multiple calls where my ID phone showed 691-4545.  This time they called themselves The Chimney Service (instead of Nick's Chimney Service) and gave me

203-208-8984

That is a real number, an answering machine for a chimney service picks up.  If they are harassing you too, and you are on the federal no call registry, you can report the company using that number to registry
