I just like to mess with them now. They call every day and I even told them NO stop calling but they dont seem to document anything and someone else or the same guy calls back later forgetting he called me already..

Heres a tip, act dumb. and be like What? Ducks? I dont have any Ducks? Why do you want to clean my Duck?

Hahahah that just confuses them its fun try it!

Just launch a complaint at https://www.lnnte-dncl.gc.ca/plt-cmp-eng if you're registered with the National Do Not Call List.

These guys are trying to get around Canada's Do Not Call List.  Start making a list and report them - would be great to get a landmark case decided against these guys.

Keep track of all the numbers you are getting called from - make a list and then contact the Police and the Governments' DNCR - and report them.  It may be it is the same people calling - but using different numbers.  They are not unlike the computer hackers - but if you don't know who is calling you from the number if you have call display - don't answer it.  Make note as above.

Just received a call but the connection was broken and all I caught was ...Toronto. Told whoever was there that the phone connection was terrible and that I could not hear them. They hung without another word.

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!
