CARTRACK NOT TREATING CUSTOMERS FAIRLY

So I've been paying for my car tracking system in my car with Cartrack for a very long time. R209 pm to be exact. Just over 3 weeks ago I call them because the location of my car on the cell phone App is always wrong. Then they send me from pillar to post until I speak to someone from their technical department. The guy goes away and comes back after 3hours to tell me that there's a fault with my device and I need to bring it in for fixing and i would have to pay for it! My question is how do i pay for something that's not even my fault? If it's faulty than clearly it's their own technical problem because I don't even know where the device is in my car! I told them I give them 7 days to resolve this or else I'm taking it straight to the ombudsmen. I want all the premiums I've ever paid them too. This is ****************!!! According to the CPA Act; CUSTOMERS MUST BE TREATED FAIRLY. Where's the fairness in all of this? Terrible service with this CARTRACK company.
