Do not install Cartrack look for something else.

I have two Scania trucks on which cartrack fleet management units have been installed. I have taken these on a 36 month contract. To date I have received a very bad service from cartrack to an extent that I attempted to cancel the contract to which I was ordered to Pay R1700 per truck. I found this absurd because of the following reasons  The units are constantly faulty and there has been no month that has gone without having either of the units working properly.  Truck 1, the unit has been faulty since the end of November 2018 and it was reported, nothing was done on the part of CarTrack to address the faulty unit. When it was reported I was told Polokwane branch will deal with the issue. I was never called until 2019/01/23 where a lady from this branch called and she was not helpful at all.  Truck 2 was reported in December that the system is faulty, to this day (2019/01/23) nothing has been done to correct the unit. As it stands the risk of the vehicles being ****** and unrecoverable is high yet I pay for a service designed to minimize such a risk. I have paid all my premiums for a service that is non existent. What have I done to deserve this????
