Call almost every day.  I am no longer polite with them and they still call.The do not call registry is a joke.  Still get all sorts of unwanted calls.

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!

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

I have received 7 calls from this number in less than 24 hours.  The person is rude when I say, "No, thank you." and hangs up on me.  After the first call, I keep getting calls where no one speaks or I am forwarded to another number as though I made a call.

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.

They called on Nov 3, 2011, didn't leave a message.  Again, this number is not recognized on 411 so I can figured who called and what they want.  Good thing I am away a lot.
