PAYING FOR TRACKING DEVICE I DO NOT OWN A CAR

I am very upset at this stage that I don't even know what to even say. when I app**** for a tracking Device with Netstar , which Netstar cannot deny that the device was faulty. and I admit to signing to a contract which was suppose to be for 24 months. so last April 2017 the vehicle was 4 years old and was involved in an accident was written off. we then had to cancel all subscriptions we had for the car. TODATE Netstar is saying I signed for a renewal which I did not I only signed a paper when the fitment centre came to install a new device for the faulty one. I been calling emailing they are telling me they are going to look into this by tracing the call which is recorded where I agreed. so PLEASE ALTECH NETSTAR CALL ME. I DO NOT OWN A VEHICLE FOR THE PAST YEAR BUT I AM PAYING NETSTAR.
