Received call and let it go to voicemail with no message being left ! I called back and the recording said that the phone number is not in service !!

905-411-2011 called and after a brief delay a woman with accent sounded Indian, asked me how am i.
I replied : i 'm okay, then shortly after hang up. I blocked her number on my Panasonic KX-TGA660C,
i won't hear that number again.

Keep getting calls from this Duct cleaning service, sometimes it's a different number, but this was the latest and they've called at least 3 times.

Should ask them to come and give them s*** next time.

we keep getting this call from 905 411 2011  and we are just tired of it... would like to stop this nonsense

WHY ??? are you people being intimidated by a phone call , grow UP, what can someone do to you by phoneing you unless you are STUPID enough to give personal info.  Play along give dumb  answers  have some fun waste their time.

Cool detailed and objective info on duct cleaning:
http://www.epa.gov/iaq/pubs/airduct.html

1 more good point:

Duct Cleaning is Rarely Necessary

A study from the U.S. Environmental Protection Agency seriously questions the need to have your ducts cleaned routinely. The EPA recommends only having them cleaned if mold exists, (ask the worker to show you mold they claim is there) if rodents or other vermin have gotten into the system and if excessive amounts of dust or particles is visibly blowing into the home from the supply registers. If you decide to have duct-work done, the EPA asks that you,"Take the same consumer precautions you normally would in assessing the service provider's competence and reliability."

(Lots of pet hair in ours, however...)

More info, a word to the WISE?!  Even tho' the Orient Duct rep repeated that not a cent is paid till AFTER the cleaning is all done, this warning could be relevant -- AN ALERT about a common Duct Cleaning scam set up with a deal that's used to run up extra charges; companies involved use many names, none of which show up in BBB reviews.:

FYI: Website for this telemarketer-represented company; NOT in BBB for my province, though.

Picked up -- and (wow, unusual!) booked an app't for duct cleaning (which we do need).  Rep very courteous and patient. Now to look up the company's records with BBB for my province.  It sounds like a good deal, actually -- even though telemarketing is not something I normally respond to favorably at all.  If any probs, will report back here!

Send a complain to CRTC.  https://www.lnnte-dncl.gc.ca/plt-cmp-eng

I just did indicating their number. If enough of us file a complaint, they will get fined. They've been calling me for over the last year now, number is usually blocked but I finally got hold of the # yesterday.

Caller did not leave a message.  Annoying telemarketers!!

Never any message, just annoying.

I am fed up with these guys.  I have told them soooo many times that I am not interested in their service.  They just keep calling and are so rude everytime. Think I might let them waste their time coming out this time only to not be welcomed in.  They are so dumb they will probably keep coming back.

Need to have them stop calling me

Just got a call from this number this morning and I didn't answer it. It has been awhile since I got a call from these A$$ Holes. I have a Panasonic phone with Call Block so this will be the only call that rings more than once :)

CBC's Market Place did a segment on this scam and can be seen here http://www.cbc.ca/marketplace/episodes/2013/01/to-catch-a-telemarketer.html if you want to know why they continue to call and why the DNC list does not and will not protect you from these A$$ Clowns..

advised that we were not interesteresponse was very abusive (f c k off) and hung up
