Terrible experience

The unit that they have installed drained my battery to the point where it is now damaged. Currently me and my family is stuck outside a restaurant waiting for someone to give us a jump start. 2 days ago they reinstalled a new unit and so far my battery is just so damaged or the device is still draining my car's battery.

When I asked cartrack if they would be replacing my car's battery due to the fact that the unit was faulty they simply refused. I can't understand how this tracking company cannot take responsibility for their faulty device
