If you tell him you have security already he says I know and would like to sell you more hidden cameras. Then I hung up.

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

First dead ari, then someone asking for Mrs. (homeowner).I told them she is not home, they said it was for our security system, and what is my name.  I would not give it to him, he said but this is about the home, and the security system, again, I said you can reach her in 2 weeks, and I am not at liberty to discuss this with you.  Again he insisted on getting my name, I told him no.  So he said, what, you don't have a name, and I said, I just do not trust you and want to give you my name.  He asked me if I was related to the homeowner, and I told him it was none of his business.

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.

Got called three days in a row from this same number.  When I answer there is no one there and then the line goes dead. Tried to call back to get them to stop calling.  Phone rings and rings then disconnects.

somene is calling and not saying anything
