Terrible Technical Department and Call Centre

I have been on the phone with Cartrack since 8:00 today. Their Technical Department is completely non-responsive. They installed the unit in a manner that it interferes with the ventilation system in my companies Toyota Land Cruiser 200. The vehicle is now with Toyota who simply requires Cartrack to come and move their unit 10mm or so that the ventilation can operate properly but Cartrack does not respond... The call centre promises to call back but NEVER does and whenever you call you speak to a different person that has no clue what the previous person did... Long story short, nothing is happening!
