Netstar panic dissapointing

I installed netstar with the panic button into my vehicle. In the beginning of January i tested my panic button and nobody called back. I phoned the call centre and their response was that my panic button has not yet been activated. Not activated after a few months. Yesterday i pressed the panic button and after 5min the call centre phoned telling me that its not a panic because my vehicle is turned off, where as my vehicle was infact not turned off, i was standing at the red robot. So the car was idling. I really am dissapointed with Netstars service. Best will be to cancel the contract and then they tell you you must pay in. For what reason your service is up to ****. Paying monthly for sonething that does not work.
