This number called here for the first time yesterday but didn't leave a message or thankfully a blank voice mail as many do.

I have noted in past if one picks up or talks to these types of turkeys the frequency of the calls actually goes up, despite telling them to stop calling.  The reputable callers will generally stop although some take a couple of trys.

Given these don't stop and as we are not in Toronto, this is probably a scam.

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.

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.

A good way is to tell them that you have geese, not ducks and ask if they can clean your backyard and roof.

same time everyday here ...and there is NEVER anyone on the line ... if someone who does get the duct company could post the company name or report it or somthing please ...although I'm sure its just a company looking for active cell numbers to sign up for premium services.. Pray the day never comes they can charge landlines!

These idiots called my unlisted number.  The first time they called, no one was on the other end so I called the number back.  Got a recording saying I could leave a message and it was forwarding me.  Then I got another recording saying that the voice mail box was full.  The second time, there was a person on the other end.  It's a duct cleaning company.  I told them to remove my number from their list.  We'll see what happens.
