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....

We're on the CRTC Do Not Call List but still these guys bug us at dinner time.  We don't need a duct cleaning svc from 200 kms away!

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

I just mess around with all these duct people until they hang up.  I like to pretend they are talking about ducks, and that I have a huge duck problem in my house.  It usually ends with me quacking at them until they hang up.  Once you prove you are a waste of time to them, they usually stop calling.

i know what the heck.....no answer, I am on sick leave so getting no sleep...my husband always askng me too who calling....

How can these pricks get away with this?
I've had six calls in the last week, and I've duly filled out the CRTC's "Do Not Call" complaint form via their website six times ... but I've had to reply or indication that anything is being done.
I'm getting pissed off at the DNC registry too.
