This number calls my house every day....a couple of times, regardless of the fact I have been asked to be removed from their list.  They hang up on me all the time as soon as I explain I had mine done recently....I am polite....but regardless they hang up on me.  I do not want them calling anymore....very frustrating.  They have different phone numbers and different air duct company names.  They have said "toronto air duct cleaning' but it changes.

got a call today, they said they offer cleaning service....

They have called me many times as well. I've tried the hang up approch, the rude approch, and everytime I try the ~I would like to know more about who they actually are~, they hang up on me. I am hoping they call agin so I can actually have an air duct cleaning service company come to my house........ I'm sure it will get interesting from there. Maybe then I can find out who gave them the tip and help bury these goof balls.

Just received a call from (416) 700-5678 and no one answered. Call the number back using *67 to hide my number. Get a message that caller is not available and am forwarded to a message stating that their message box is full. I too am on a no call list.You can congratulate the caller and inform him/her that by violating the guidelines of the CRTC's no call list that both he/she and company are now eligible for a fine by the CRTC to the tune of 4,0000 per violationIf I get any subsequent calls, I will pretend to be interested enough to get the companies name and number and then procedd to contact the CRTC by fax or email and lodge a formal complaint that the caller has violated "The No Call List". !

Dont bother with them they are scammers

They called on Nov 3, 2011, didn't leave a message.  Again, this number is not recognized on 411 so I can figured who called and what they want.  Good thing I am away a lot.
