Unfair practice towards consumers

I took out a tracking device with tracker a year back. I have now traded in my car and bought a new one. Now I have been advised if I transfer the contract I will be charged and if I settle the contract i will be charged. However, either way I do not get to own the unit. I do not think this is a fair practice for consumers. I am willing to pay for a service or a unit but I cant be charged for both if 1- I wont get the unit 2- wont be using the service.

And on top of it I am paying insurance for the unit which I do not own.

I would not recommend tracker and wont use them again.
