This number called here for the first time yesterday but didn't leave a message or thankfully a blank voice mail as many do.

I have noted in past if one picks up or talks to these types of turkeys the frequency of the calls actually goes up, despite telling them to stop calling.  The reputable callers will generally stop although some take a couple of trys.

Given these don't stop and as we are not in Toronto, this is probably a scam.

They have called me some many times in the past 9 months.  I ask them everytime what company they are calling from, and everytime they give me a diferent name.  I have even googles the company name while they were on the phone and told them ithat name does not exsist, and they hang up on me.  I tell them "yes, I am interested, but I will have to call your office in the morning, what is the number?" and they give m a fake number.  I now just tell them that I have called the police and they know who they are, and they hang up on me.  I even went as far as telling them, yes I want the duct cleaning service, but I have to talk to a manager to sort out the details, and they hung up on me.  All calls are coming from India, I am sure.  But I can't figure out what their scm is.  I know for sure it is some kind of scam, but I don't know what!

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.

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!

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.
