These "Duct Cleaners" have been calling me every couple of days for several weeks. I started out very calm and polite. Told them my ducts were just cleaned - they hung up. Told them Asked to be taken off of their call list - they hung up. I'm sure the stories are all the same. Decided to tell them that I am busy at the moment but would like to call them back to discuss - asking them for a company name and phone number - which of course they won't give... they would prefer to call back. They told me the name of the company is "Duct Cleaning Company". haha. Now they swear at me. Good grief.The hang ups were annoying... the filthy language unacceptable. Great business model. I urge everyone to keep them on the line for a few minutes.. ask them what the name of the company is. Ask about pricing... get them to go into detail. Eventually numbers will be cleared from their list.

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!

They have called me every day this week between 3:50 and 4:05 p.m.   Same thing, when we pick up there's dead air.    I call back and get a recording that it's going to voice mail then the voice mail is set up to say it's full.

I, too will find their company information and report them.  I am also on the Do Not Call list, it has stopped about 95% of the scammers but these guys somehow get through.

What do they possibly get out of calling and saying nothing?  They certainly don't drum up business???

just tell them to @#@# themselves with their hose.  they get the point.

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.

The DNC is a list that telemarketers are suppose to update once a month. Once they get the list, they usually have to be manually inputted into they're calling system so the computer doesn't dial your number. But that's the catch: They have to get the list from the CRTC. If they are from a calling center overseas, the CRTC can't monitor or enforce the rules on them. That's why most companies are getting these call centers overseas to do their telemarketing.
