Someone just called very rude and starting swearing and acting stupid.

Just logged a complaint on the Canadian Do Not Call Registry.  If you have not already logged your phone number on the Do Not Call Registry, then this is one way to stop these types of calls.  On this same website where you register your number on the List, you can also log a complaint about a telemarketer such as this one.  I have just renewed my number on this list (it is good for a few years) AND I logged a complaint with the CRTC about this jerk.

Asian sounding caller wanted to know about my security. Told him of the no call list kept insisting I was not on his list. Told him to delete me from his calls very argumentative repeating my security system. Again told him to delete me from his call list or I would report him to the national do not call list. Kept arguing about my security system. Hung up on him before telling him that I would report a complaint about him which I am just about to do.

The best thing to do is to get as much information and then lodge a formal complaint as he just wants to wear you down and argue.

This idiot calls every day around 7pm and hangs up. Maybe if I answered in Urdu, or Hindustani, or Farsi ....but I answer in English and get "dead air"

same kind of call did not answer myself answering party when asked about security said not interested, woman caller this time, unfortunately did verify name of houshold, will let local police know concerns
