Keep track of all the numbers you are getting called from - make a list and then contact the Police and the Governments' DNCR - and report them.  It may be it is the same people calling - but using different numbers.  They are not unlike the computer hackers - but if you don't know who is calling you from the number if you have call display - don't answer it.  Make note as above.

I've submitted a complaint through the CRTC National Do Not Call List service.  Don't know what will come of it but I've had enough of this over the past several weeks.  Fingers crossed....

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.

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???

Dont bother with them they are scammers
