BAD SERVICE FROM CRYSTAL

Very bad service from Tracker, the consultant by the name of CRYSTAL is absolutely rude and arrogant. After having bad Tracker fitment from a tracker installer almost two years ago, i could actually hear the tracking ratting and making a sound in my vehicle. Crystal has the the audacity to say that i have no way of proving that the tracker installer did a terrible installation.

THEN HOW DO I NOW KNOW WHERE THE TRACKER IS IN MY VEHICLE ??
