Not getting what I pay for?????

I have had a tracker installed in my vehicle for just over a year now. I am now getting false reports from the unit and the attitude that the staff at tracker give me is a basic \go to hell". All ghat they can say is sorry that the system is not working 100% but we can charge you to have it checked.. As per our terms and conditions the warranty is 1yr and after that it is no longer Trackers problem... What do I pay for? Just to be able to see what is happening with my bakkie and for Tracker to be able to monitor the bakkie. So tell me how accurate can the system be and how can tracker give me what I pay for if the system is sending out false signals? This tracker says is not their problem as they will not send somebody to check the system with out me the paying customer does not pay more for them to ensure that their system works correctly. With that Tracker gives me the feeling that they do not give a f_-_ about customers and just money. Who cares if the system on a R500 000.00 vehicle does not work correctly..... Not tracker that's for sure. Pay us or we will not help you further as per our terms and conditions. Nice view to have on customer service. """
