Tracker's Customer Support is sadly lacking

The Customer Care function at Tracker is problematic. The tracking device in my daughter's car has not been working for the last 7 days. The unit is still under guarantee. I had contacted Tracker's Customer Care line on 24, 26, 27, 28 Feb. Every time I was promised that a technician would contact we to make arrangements to address the fault. To date I have not been contacted! This is rather unprofessional. I would not recommend the company to anyone. The technology may be good but the support is sadly lacking.
