These idiots have called my house way too many times.  And every single time I ask them to take my number off their list, they hang up on me before I even have a chance to finish my sentence.  They are rude and inconsiderate, even after I tell them that my number is on the CRTC do not call list.  I've made a complaint against them to the CRTC, hopefully it won't take too long to have rectified.  In the meantime, I've blocked their number.  Hubby made a good suggestion though, next time they call, make an appointment to clean the ducts and then when they show up at my door, I can personally tell them where to go, maybe that will be my new approach to these rude and annoying telemarketers.

just tell them to @#@# themselves with their hose.  
they get the point.

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.

same time everyday here ...and there is NEVER anyone on the line ... if someone who does get the duct company could post the company name or report it or somthing please ...although I'm sure its just a company looking for active cell numbers to sign up for premium services.. Pray the day never comes they can charge landlines!

These idiots called my unlisted number. ?The first time they called, no one was on the other end so I called the number back.  Got a recording saying I could leave a message and it was forwarding me.  Then I got another recording saying that the voice mail box was full.  The second time, there was a person on the other end.  It's a duct cleaning company.  I told them to remove my number from their list.  We'll see what happens.

I've submitted a complaint through the CRTC National Do Not Call List service. ?Don't know what will come of it but I've had enough of this over the past several weeks.  Fingers crossed....
