Car track, shockingly poor service

I am an existing car track client have recently purchased a new vehicle. I scheduled removal of the unit and fitment into the new vehicle. The technicians did not arrive even though I had made it clear that timing was critical and followed up more than once to confirm.Today is the 6th day that this simple task is not done, This is after a number of calls and promises from car track personnel, and even escalating the matter to higher levels with cartrack ranks.
