I am still waiting for a technician

Now this is a very bad experience on my part....my mum's car which is an audi A6 has a fitted tracking system which we arm and disarm. The battery was taken out of the car as it was used to help my sister who needed it at that point. Since the battery has been put back in the car we are still not able to arm and disarm the car which means it's not safe. We have called the service desk on numerous times and still the problem has not been sorted. To such an extent that one of the ladies advised that we should drive to the fitment centre and have the matter resolved. I contacted netstar on Thursday and requested that a technician be sent to the house to check the device...The name of the consultant is Jabu and he advised that he will keep in touch as he was not sure when the technician would come through...its Tuesday and still no word from him. Now my mum can't use the car because she works at the mall and there she's scared that should the car go missing the insurance provider won't pay for theft as per the clause. I need this fixed asap or else I will move to a better service provider. I am cancelling the debit order until the matter has been resolved.
