Bad attitude with undermining and less than poor customer service

The admin lady who schedules appointments at Tracker's Onestoptracking workshop at The Glen (Johannesburg South) has a bad attitude that should not be experienced by customers. I tried to arrange for a Technician to check my faulty tracker system at our company premises but the lady refused and told me I would have to bring the car to the workshop. When I asked why the Tech can't come to our company premesis she told me it can't be done there, even when I told her the system was installed at our company premesis at the 1st place she still refused. And she also refused to disclose the reasons why it can't be done at the company premises. It is only when I asked for her name that she changed her story and said she would send a Technician to our company premises. And she actually refused to give me her name as I mentioned to her that I wanted to report her to Tracker Customer Care. Her attitude is not one that shows she values Tracker's Customers and she could not care less about the convenience for the customer. The matter has been reported to Tracker but no one has called me about the incident.
