Irritating services from Cartrack

Cartrack is full of nonsense. They are ******, I wanted to downgrade my device after they have 9fferd me to upgrade. I bought a second car and I feel I am now paying for the service I am not using. Called them sometime ago in the last 3 weeks. I spoke to a service champion and she advised that she will call me even today dololo. She said I cannot downgrade my device, of I insist I will have to pay more to downgrade. Which is not fair for me because they are the ones who called me and offered me the services. Now that I don't want them I have to pay.
