Disgusting + unfair customer service

I has cartrack installed and my car was ******. Car track only notified me once the tracker was removed. The car was later found but totally stripped. No doors, no engine, no chassis. Literally every nut and bolt was removed. Now I need to cancel my car track because I don't have a car and car track wants me to pay R1700 early cancelation fee because they feel they did their job by finding my car. The car was not found! The s**** metal was found. Very unfair! Firstly I wasted all that money paying my monthly installments and now cartrack wants me to pay an early cancelation fee? I wouldn't be canceling if cartrack did their job and found my car as a car! Or if they picked up that my car was ****** before the device was removed. So unfair!
