Cartrack Client Services not available for clients

I have a number of trucks on my profile and one if them is not showing real time on my App. I called several times to rectify this and Cartrack keep on insisting that there is nothing wrong. I spoke to an Agent by the name of Welcome and when I requested to speak to a Supervisor or Manager, I was put on hold for a long time until I ended the call. The service is pathetic, you are quick to schedule an appointment for fitment if its new business and you are not available for maintenance of your units. And your Managers are too important to speak to Clients. I am on the market to look for an alternative service provider who values my business.
