Same thing, they call, there is no one there, even if you wait and keep saying hello, the computer never seems to forward it to a live human. If I ever get a human, I am just going to go along with it till I get the name of the company, then report them.

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???

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.

All u tell them what i told them. I let them speak there bu***hit and then i told them i'm in appartment 1702 . They should get the message.

Getting the same annoying calls. When I answer no one is there. I do subscribe to the Do Not Call list. Thus there will be a report to the CRTC

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.
