This is a telemarketing company for a home alarm system. ?How is it that they don't respect no call lists?  Very irritating especially that they use an automated dialler system which provides dead air when you answer.

This is a con... they want to know if you have a security system in place etc so they can rob your house..Do not speak to them at all. Suggest you go to the nearest police station and report this incident with the phnoe number so you are covered in case of a situation,

somene is calling and not saying anything

(416) 342-1522 calls and some person with a foreign accent tries to sell a security system or replace what you already have. The worst part is that they then want to know the details of your current security system too. We received 4 calls over the past 3 months

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.

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.
