Not an armed service - an alarming money making scheme

I have complained a lot about their services. They always promised to better it. Recently had them call me more than 30 minutes after an alarm activation. Sent them an email. A week later the manager calls to apologise and ask that I do not cancel the contract and give them time to improve. A few days pass after this promise. This time they call us a little under 40 minutes after the alarm was activated. Armed response arrives1 hour and 2 minutes later. You will literally be throwing your money away if you sign up for their 'service'. Let's see if they actually action my cancellation notice within the mandated calendar month.
