Security Concern

I have had an account with Netstar for years and every time I sell a car it takes months to get it off of my account. I call them, I email them and still after about 6 months, I have my old car on my app, I'm still paying and they don't contact me. The same happened the last time with a previous car until I came to Hello Peter. The cancelation of a car on their apps etc is very user unfriendly. The fact that I know where this car is, imagine the new owner's concern if he new I could track him. PATHETIC SERVICE!
