Netstar *******

Im very disappointed with Netstar. I have ask for re-installment of a tracker in my new car, they created a new contract for me instead of transferring the current contract. now im stuck with 3 contract that i need to pay every month. I only own 2 cars but im paying tracker fee for 3 cars which one of them sold last month. I have called several times but no one want to help me. I even have a ref no (CAS-***-V9W6)
