CONTINUOUS FALSE ALARMS

I INSTALLED A NETSTAR TRACKING DEVICE IN MY NEW CAR LAST YEAR AND FROM THE FIRST DAY IT TRIGGERED FALSE ALARMS. THE UNIT IS CLEARLY FAULTY BUT THEY PHONE ME MOST DAYS WITH A FALSE ALARM. I'VE BEEN IN TOUCH WITH THEIR INSTALLMENTS AND CUSTOMER SERVICE DEPARTMENTS WHO ASSURE YOU THAT IT WILL BE SORTED BUT THEY NEVER EVER DO. WITH EVERY SIGLE FALSE ALARM I TELL THEM TO ARRANGE FOR IT TO BE SORTED OUT BUT THEY NEVER EVER DO. <br>
