Terrible service in all regards

I have a Netstar eraly warning tarcking system in my vehcile. From the start I have struggled with false panics on the system the moment I drive my car. It is extremnely annoying to haver to expalin the sistuation to the call centre every time this happens. The Netstar "technicans" came out twice to fix the issue but both attempts were unsuccesful. The problem persisted and every time I got a call from the call centre I informed them of the false panic and that someone needs to come and try to fix it a third time. This never happened until this week when Netstar finally made contact again to tell me that my device is now out of warranty and it will now cost me in excess of R700 to fix the problem. This is laughable so I will be cancelling my services and moving over to another service provider.
