Paying for non working alarm

We installed a Chubb alarm after Andre the consultant recommended it as the best. We paid - R25 000.00 that was Sept 2015 and thorough out the remainder of 2015 we had more than 3 technicians coming to the house to fix the alarm because 1. The alarm would go off after arming it costing us to have too many false alarms and being charged after three visits. First they blamed it on the birds. 2. The alarm was \fixed\" but to our horror the alarm was triggered mistakenly and the control room didn't contact us. I called to enquire why & was told no signal was received.<br> I have been paying for the alarm and we didn't have armed response available. Finally a technician came to diagnose the problem in January 2016 noted that our signal strength for one beam was at 1/10. He stated we needed a repeater to increase signal strength we waited for a month before a repeater was installed on 08 April still paying For no cover at all. The alarm was accidentally activated on the 09 April & control room didn't call us to find out if we are safe. I have been calling the technical department since 08:00 11 April but I can't get any confirmation as to when will a technician come to fix the problem again"
