Chubb broke my alarm and charging me for monitoring for months that I'm not receiving

Really bad service. In November 2017, Chubb technician Glen came to install a monitoring device. He signed off the job and no monitoring was happening. Today, 19 February 2018, he comes for the fourth time to fix the monitoring and still doesn't get it right. To make matters worse, now my alarm is not working. All I asked for was for armed response, and now I don't even have an alarm that works. All this while I'm paying my monthly service fee. Since November until now, now monitoring has been happening and after today, no alarm either. Really bad bad bad service. I've been on the phone for over and hour. Your standby technician tells me his manager said he can sort it out tomorrow. My money and business was good enough for the contract, and that's about it.
