CARTRACK DOESN'T CARE!!!!!

I'm so disappointed with CarTrack. I traded in my old car and called Cartrack to advised them of this and told them I want to continue with my account. I was told I need to pay R800 to install a new device in my car and was told that they must remove the old device from my old car and re-install it in my new car. I was so surprised cause my understanding was that the tracking company will deactivate the old device and install a new one, hence the R800 fee. I've been driving a car without a tracking device because they can't get hold of the dealer. So why must I pay the R800 if they'll be using the same device from the old car, and while trying to get the old device, what about the safety of my car!! I'm actually shocked that tracking companies can put their customers in such danger!!!!!
