High insurance premium due to non-functioning unit

I received my new vehicle on 27 November 2015, which has a Tracker SkyTrax unit installed. I noticed four days later that the SkyTrax unit wasn't updating the vehicle's location. I called numerous times, after which a request was submitted by Tracker head office to their branch in Pretoria, in order for them to physically inspect the unit.<br> <br> Given that I now have to pay approximately 40% extra for my insurance, as a result of this unit that it isn't working, it is only understandable that I want this problem sorted out immediately. <br> <br> I was told that I'd receive a call from their Pretoria branch by the end of today. However, nothing thus far. I called head office again, and they now say it can take three working days for the Pretoria branch to just call me to make arrangements - even though the matter was \escalated".<br> <br> Tracker - if you are prepared to manufacture garbage products"
