Received 4 calls within 20 minutes from (416) 900-3699. Caller ID shows "Security Alarm" Called the number back and let it ring for 15 minutes. Gentleman answered and advised him that I was on "Do not call" list and he claimed he would remove my number from their list immediately.
Guess we will see.

Called but did not leave a message.  Wea are on the No Call List.

got a few calls from this company. reliance security (416) 900-3699then funny story.. when I said that my alarm system was two large dogs, I got robbed 2 days later.coincidence?anyway, I asked to be removed from their list as we are on the do not call list

Interesting I was looking up this reliance security and found this post.  They were prying into my security system also.  Did the police investigate this?  It seemed like a scam to me also to find out if I had a security system.  Phone number (416) 400-4968
