Technician wiped system and refuse to help

I wanted to deactivate a safe zone and the technician gave me a wrong code ( I think deliberately) and wiped my entire system. My remotes doesn't activate/deactivate... I don't get any responses when the alarm or panic buttons are triggered......For the past 2 hours I have been speaking to the entire call centre begging for help and all I get is that I need to book a technician to come to me after a week and pay R1000.00... And now I'm paying for a red flashing light and NO security. This puts me and my family at risk. In the event I suffer a loss my insurance will not pay out because of faulty equipment. Then trying to get the number for the complaints line and the call centre agent tells me he doesn't know it... seriously?????
