Useless callcentre

<p>We have 8 vehicles using x-drive from Mix Telematics. One of the vehicles is stuck on the 26th of July and won`t update(3 days already). Yesterday I called their callcentre and was transferred to SEVEN diffrent people. After 25 minutes she told me she will reset the unit. Well one day later and it is still not working. I think the people are *********** and useless.</p>
