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.

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

i know what the heck.....no answer, I am on sick leave so getting no sleep...
my husband always askng me too who calling....

I just had these people call and ask for the home owners. When I said they were not available they and asked to take a message they replied with "This must be their lovely daughter". I replied with "yes, can I ask why you are calling?" and the response I got was "What's your name? I'm calling because I really like you". This number continually calls my house and either there is no one on the other line or they get angry and rude when I say I am not interested in their services. Can something be done about this so that they stop calling? I'm getting very annoyed by the calls.

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.

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