I have been harassed by this company now for over 3 years.  I think it might have started when I filled out a home show prize thing. I have repeatedly told them, as others in this thread, to stop calling me.  It is becoming a severe problem.  Harassment pure and simple.  They are from Florida.  I was told to F, off by one of the marketers.  It's always the same one.  I now won't answer the phone, and even if I did need anything, I wouldn't get it from them. Period. Worst sales ever. I get windows and doors, but it's switched from Air Duct and back.  Also, the different numbers.  Thank you for listing. I will be contacting Bell, apparently you can have it blocked by them. But, I don't know how long this lasts.  Makes me not want to attend a home show ever again.

Sales call from "Air Duct Cleaning Service." I told them (yet again) to stop calling me. They just keep calling !!!  I am on "NOT TO CALL LIST", but it doesn't make any difference !Government should do this illegal !

Sales call from "Air Duct Cleaning Service." I told them (yet again) to stop calling me. When I called the number back, it was an unassigned number.

George.....Thanks for that info.  I have a panasonic phone that blocks calls free of charge.  The only problem is it can only do 30 phone numbers at a time.  The ones you listed will take up almost half that on my phone....hahaha  Why is the CRTC not going after these guys.  I am so sick of being called.  Actually, I think at this point, the only calls I get are from solicitors.  Hey I might get rid of my phone!

This time they said they are from :Air Duct Cleaning ServiceBut ever time they call it is a different company name or even phone # but I know it is the same company.They even useD BLOCK CALLER.They use VOIP and fake the number and name.I tell them I do not need duct cleaning, they still call.I tell them that I already had it done, they still call.I tell them I used an another company, they still call.I tell them I will never ever use their company, they still call.THE DO NOT CALL LIST IS A JOKE, THESE COMPANIES ARE USING THE LIST TO CALL PEOPLE.THIS COMPANY WILL STILL KEEP CALLING UNTIL THE PHONE COMPANIES ARE FORCED INTO CHECKING INTO THIS, BUT THEY WON'T BECAUSE THEY WILL MAKE MONEY FOR THE PHONE CALLS AND FROM CHARGING YOU FOR NUMBER AND NAME DISPLAY.HERE ARE SOME OF THE NUMBERS THEY USE.(416) 333-98501-(905) 520-9664(416) 725-5283(647) 739-2289(647) 800-2369(905) 267-1263(905) 460-5825
