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

Just received a call from (416) 700-5678 and no one answered. Call the number back using *67 to hide my number. Get a message that caller is not available and am forwarded to a message stating that their message box is full. I too am on a no call list.You can congratulate the caller and inform him/her that by violating the guidelines of the CRTC's no call list that both he/she and company are now eligible for a fine by the CRTC to the tune of 4,0000 per violationIf I get any subsequent calls, I will pretend to be interested enough to get the companies name and number and then procedd to contact the CRTC by fax or email and lodge a formal complaint that the caller has violated "The No Call List". !

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

So what company or service are they representing?
