3 Months and still waiting

Hi,<br> <br> In Nov 2014 I arranged to have a tracker unit removed from the car I was selling. Since then it's been an uphill battle to have the unit removed from the car. The removal date has been changed 3 times already and every time Tracker does not honour their promise. The new owner is now complaining about the unit draining his battery and he has returned the car back to me for a week to make a plan for the removal.<br> <br> Can somebody who actually cares about their job give me a call? I have wasted so much airtime calling Tracker for this simple task.
