Dismal Service Cartrack

we have a fleet of vehicles with cartrack , we have one vehicle that has a faulty unit in it, this unit causes the vehicle not to start as it has a cutout.

We cannot use this vehicle in our fleet and have been informed by cartrack that we can wait 2 weeks for its repair.

Who is going to pay for the loss of income as we cannot use this vehicle in our business and cartrack have admitted their unit is faulty ??
