I just mess around with all these duct people until they hang up.  I like to pretend they are talking about ducks, and that I have a huge duck problem in my house.  It usually ends with me quacking at them until they hang up.  Once you prove you are a waste of time to them, they usually stop calling.

Just launch a complaint at https://www.lnnte-dncl.gc.ca/plt-cmp-eng if you're registered with the National Do Not Call List.

Dont bother with them they are scammers

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.

The DNC is a list that telemarketers are suppose to update once a month. Once they get the list, they usually have to be manually inputted into they're calling system so the computer doesn't dial your number. But that's the catch: They have to get the list from the CRTC. If they are from a calling center overseas, the CRTC can't monitor or enforce the rules on them. That's why most companies are getting these call centers overseas to do their telemarketing.

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". !
