Cartracker is *******!

I am livid, my car was written off in October and insurance claim finalised in November, I informed car track that I do not have a car and wanted to cancel my contract. Was advised that I will not be able to since it’s a 36 months contract so I need to keep paying for that. December I got a new car, advised cartracker of this and they advised that they would have to deinstall the tracking device on the car written off car and reinstall in the new car. They went on to deduct R920 for this deinstall and reinstall. As we sit today they have not yet reinstalled the device on the new car, they keep telling me that there is no technician in my area, this happens after they have rescheduled an appointment and not pitch up and when I call they tell me this, they do not bother to inform me that no one will come out on the scheduled date. My car is without a tracking device which puts myself in great danger because it is an insurance requirement and should anything happen to the car I will not be covered. I have been at they beck and call but they have the rudest staff ever…can they just cancel this contract, they have not been able to meet their end of the bargain and the staff tell you straight that even if you speak to a supervisor they will tell you the same thing…I am more than annoyed!
