Waiting for technician for a week. No way to get an answer from anyone

I have been contacting your call center for a whole week and everyday trying to find out when I can expect your technician to come through to remove the tracker on my car in order for the car dealer to do the battery test. There is no way to get that information. Your call center staff calls and sends emails to your Cape Town technician team but no response at all. I have repeated my store with so many of your call center staff although they all trying to be helpful, there is no solution offered for me. Now I have been almost two weeks without my car. Please can someone who knows what is happening send your technician through and let me know?
