Horrible service

Horrible service from cartrack : A week ago I contact cartrack regarding my tracking which is not working, something they did not pick up on their side and can not answer as to why, till date I have not received feedback or a resolution from cartrack, I have spoken to Magabane and requested to speak to a manager, Magabane gave me several reasons as to why his manager is unable to assist instead emphasized that he will be bpenalized if I have to speak to a manager. It would seem requesting to speak to a manager at Cartrack is not an option when a client has a concern and wants to raise a complaint, another concern is how cartrack deals with their customs concerns, surly this is not business ethics? The obvious benefit of vehicle tracking is that it provides real-time tracking of vehicles, this is a basic service which cartrack fails to provide their paying customers. Not sure what I need to do to get this issue resolved?
