According to GZ we can report faults with the T-Box here instead of wasting time queuing on your 0800 number.
Be carefull, while posting it on here to get feedback or advice from Gary and other TCL boffins might prove helpfull, I very much doubt your forum post will count if you ever decide to take action to recoup your $499, or ask for a credit to your account for hassles endured.
As much as its a 40min pain in the ass, your need to log the calls to keep a paper trail.
Moaning to the Small Claims Court that "it failed ever week!", but TCL can show you only called for 1 issue over 18month (for example) will see you lose every time.
Trust me, I've been there....
