DONT GO NEAR NETSTAR

Anyone looking for a vehicle tracking service? My advice, DO NOT GO NEAR NETSTAR. I have been trying for months now to cancel their service on a car I sold, and it is IMPOSSIBLE. They simply ignore emails, and when you phone them they promise to cancel the service, but just keep on with deductions. THEY ARE USELESS. Not to mention the number of false alarms/notifications about my vehicle while I was using their service!
