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....

These a****oles call me as well in their fake p*** voices...No Call List is crap..Hope they call again because I have a plan....

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!

My husband is very ill, we aren't getting much rest and these idiots keep calling but never speak to us.

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.

Getting the same annoying calls. When I answer no one is there. I do subscribe to the Do Not Call list. Thus there will be a report to the CRTC
