Tracking Unit not working

<p>I had an appointment to have the unit in my Isuzu replaced last Thursday, the 8th of December 2012. Nobody showed up nor did I get any communication saying that it was cancelled / postponed. I've phone twice and left a 'Contact Us' message but nobody has come back to me regarding this issue. I've been billed for paying for this non-delivered service for close to two months now. </p> <p>If my car gets ****** and the insurance tells me to get lost because my tracking unit wasn't working, I will be forced to get a lawyer to sue CarTrack to replace my vehicle.</p>
