ADT Bad Service, not trustworthy

I installed ADT system. Well the first night I was testing and the no response. Then my alarm went off in the middle of the night. Still no response from ADT Patrol car. I called them. Well they were not receiving a signal on their side even though the system was tested after installation. The last time they received signal is when the technician was testing after installing. I requested that a technician is sent to look at the fault. I was told that there's Technicians on standby. However none were available. ADT couldn't get hold of any of the standby technicians. So what is the point of having standby technicians if you can not get hold of them when you need them? Tell me that?<br> I was very disappointed with a lack of service. So I have requested ADT to remove their system and I am having a professional and customer focus company to install a security system. Today the technicians came to remove the system. I got a call from ADT saying they are receiving a signal from my house. I told them that their Technicians are on site. No they don't have technicians booked. Really? It turns out indeed their technicians are on site removing the system. What a bad service. I just want refund.
