Hassles with tracking unit

I am a client of auto &gen for more than 2 years. I recently traded in my old vehicle for a new one. When I called to cancel my insurance for cheaper cover elsewhere, they immediately cut my premium in half. However I had so much hassles with the tracking unit. I had a tracking device on my old vehicle and what they do is tie you to a 3yr contract. (So if you sell your vehicle then you must still be liable for the balance of the contract even though you don't have a vehicle?) I wonder if this is even legal. I needed the tracking device moved from my old vehicle to my new vehicle but the consultant did not advice me that there is a large fee for doing that as well (labour fee). Then i find out that the tracking device was not even loaded onto my vehicle insurance cover, even after 3 phone calls with the consultant. Here I am paying for a tracking device (or thinking that I'm paying for the device) but that information was incorrect. I've had to phone back and forth between netstar and auto and gen without any help. They really need to improve their communication with clients in telling them the correct information. I am now driving a vehicle without a tracking device that I asked (and confirmed that it will be) to be kept or transferred when I accepted the insurance cover with auto and general At the new premium over the phone. I asked multiple times if my benefit is kept the same even at the sharply reduced premium and they confirmed yes, but in actual fact the tracker was not loaded and they did not even have a clue what fees are related to the tracking device that they organised for me on my old vehicle
