Had a call from this number.  Rude and abusive staff told me to go F**K myself when I asked for the name of the company Then read my address to me and told me he'd send someone to the to the house to F**k me tomorrow.  I called the police and filed a report. Not sure if it will get me anywhere.

A man called at 8:22pm the first time no voice return, they called right back and asked for Sean and "How are you today?". Sean replied "I'm having the best day ever!" He said "what is that?", lots of background noise as if he was in a public place. He asked if Sean needed my air ducts cleaned because they are having a promotion in that area, Sean had asked why has Sean been called 3 times about the air ducts this week? His reply was "what?, do you want your air ducts cleaned or what? in a snappy manner" Sean asked "Is that how you ask for business?" he said "what a f*#king @ssH*le!" then hung up!

When you call the number (905) 436-4489 you get a message to go to their website ontario.ca/revenue

A guy named Jason( I dont think it is his real name,) called at 9.00pm  from (905) 436-4489 and asked for the owner of the home.When asked for the name of the company,said some duct cleaning services.When I informed that this is an unlisted call and that I have previously complained to the BBB, he started talking in some other language( sounded an Asian) and there were a lot of noise in the background.When called back,a message goes saying this number is not accepting any messages. We get about 10 calls from different duct cleaning companies and this is a real nuisance. Even authorities are deaf  and complaining is like playing to a deaf galary.
