This is a company called Air Duct Cleaning Services - I have spoken to the CRTC and it is a fraudulent company and I have reported them.  Suggest you do the same.

Recieved same call in Ottawa. I have heard the voice before. He also told me he does not abide by Canada laws and can not be touched. He ended the call by telling me I could F.... myself.
I should just hang up and not let these people get to me.
