Received a call about 5 minutes ago. Some guy called Charlie who said something about a "police system". (I think he meant an alarm system monitoring service.) I said no thank you and he said he was not selling them. Still said thank you but no thank you, to which he replied "Fine then" and that was it.

Call from 613 662 1570 a few minutes ago trying to sell Alarm systems. started off by saying that they noticed I had purchased an alarm system over 3 years ago to make it sound like they already knew. Fortunately a bad connection a lot of static on the line, I had to put the phone down

Received a call from this phone number a few minutes....this was the third time in three days.  He said I needed to change my alarm system as it was more than 3 years old.  I said no thank you but he wouldn't stop talking.  I said no thank you again and he said I had to upgrade and again I said no thank you.  He kept talking and would not take no for an answer so I finally hung up.

Same here.  Said alarm system was more than 3 years old...how the heck do they know that??  Had to hang up on "Adam".  They've been calling twice a day for the past 2 weeks..

Just had the same call from "John".  He said he was calling from Ontario Home Alarm Systems.  He asked me if I had an alarm system for more then 3 years.  I asked him why he was calling and he just kept repeating the same question.  I told him I was not going to answer his question until he answered mine and he finally hung up on me after going around several times.  These people need to get a real job!
