Netstar after 6 years just not good enough

I have had just about enough of Netstar. Yesterday my netstar tracking device alarm went off when i switched my car on as it did not disarm from my alarm signal. No one called to make sure i was alive and well. Hours later i decided to press the panic button to test and to my horror again no one called. I would have called but over the last 3 to 4 test calls i made to Netstar they failed to find my details on the system. I requested a call back from customer care once again to no avail. Im sure if i stop paying my debit order you will find my details very quickly
