NO SERVICE ONLY HAD THE SYSTEM 2 WEEKS

Installed a Alarm system at my house. It has been faulty for the past 2 weeks since install. Faulty alarm codes coming through and chubb doesn't come out to investicate. the installer didn't installed the system correctly. Now i have to get calls 4/5 a day about a ******* alarm. my alarm is disabled and we are at home. The supplier / installer keep on puting wrong radios in the system and i found out that the system is rent to own after i paid nearly R4500 FOR IT. Which were never informed to me in the first place. I want this sorted out Between Chubb and ADY ALARMS. TODAY STILL
