Poor service by Cartrack consultants

I am really disappointed of the level of service from Cartrack, it is extremely poor. I have a query regarding the premium they are charging which it is not what i agreed on. I have been trying to resolve this matter for a week now and still don't get the necessary assistance.

I still don't have the assistance i need regarding my account and they just don't care
