Terrible installation and impossible to get it rectified

<p>Had an Altech Netstar Early Warning Unit fitted by Netstar who outsourced the installation to car sound and security. The unit in a high risk car was installed right behind the battery, took another technician 2 minutes to find. Have made numerous calls to get Netstar themselves to come and reinstall but nothing. Makes me think they not interested if the car gets ******? Not my first issue them either last time had to escalate to management to get a faulty unit replaced. Wish I had learnt and use someone else.</p>
