Cartrack Sold My Car Tracking Device Without My Consent

I have submitted a de/reinstallation request to CarTrack and was told the process will take a week. 7 weeks later, after countless back & forth calls with their customer service agents. I got a call from Cartrack customer service informing me that the owner of my old car (Audi) would like to keep the tracking device. The same tracking device I requested to be uninstalled. I rejected this and requested that we proceed as per my original request. Tell me why I'm still waiting for the fitment of the tracking device on my new car. THEY SOLD THE TRACKING UNIT AS A PACKAGE TO THE OWNER OF MY OLD CAR. NOW I HAVE TO COUGH OUT MONEY FROM MY POCKET TO START A NEW CONTRACT DESPITE BEING WITH THEM FOR OVER 5 YEARS.
