R850 tracking device transfer???

After being a car track client for the passed 3 years I called in to transfer my tracking device to a new car I will be purchasing. I’m told in order for me to remain a client of car track I would need to pay R850 to transfer the tracking unit to my new vehicle. I’m not obligated to take up the car track service and I’ve put off by the attitude of cartrack thinking they’re doing me a favor by me paying to use their service. The reason I adopted cartracks service was beacause my insurer Kingprice had arranged for my vehicle to be fitted with their tracking device. Cancelling my subscription with car track and taking up new vehicle tracking options seems like the best thing to do. Was also told at 9am on Monday morning that a manager would call me back to discuss this and this is yet to happen.
