What's point of a tracking device that doesn,t work?

Dont ever think you safe when you have a unit from Tracker. If you get hijacked its going to be between you and God because their systems dont work. It has been 3 days and they havent located my car. What's the use? Dont get me started on the billing issues. They cant even get that right but they are good at getting your money. If you want to be safe and avoid headaches, stay away from this company
