I signed up with The Monitoring Center about 3 years back. Most of the time they would call when an alarm is tripped, but there have also been a few horror stories that make me question the service they provide...
1. I have tried to test their monitoring be disconnecting the power to the panel and I have not gotten a call asking if everything is ok.
2. Once, an alarm was tripped, they tried to call the house phone which we did not pick up in time, then they called the 2 cell phones in the call list, but it went straight to voicemail because of bad reception at the time. That was the end of them trying to reach us. They did not leave any voicemails, nor did they call the police. They just stopped trying to contact us after 3 tries which is UNACCEPTABLE!
3. An alarm was tripped twice and they just did not call at all!
4. I went on vacation for a week and did everything to tell them that I will be away for a week and the police should be called if an alarm is tripped. Everything seemed to be in order, but they called me on my last day of vacation. So I had to spend long distance charges to call them back to inquire. It turns out to be their accounting department asking for a York region fee that was due in 1 month. I told them that I was displeased with the lack of communications between departments, but they did not care and am still waiting for a callback after 3 requests to speak to a supervisor.
I have had enough of this bad service and I am currently looking for a new monitoring company. I guess you definitely get what you pay for.
