Appalling service - Repairs to vehicle

It is extremely disappointing that as a client of Telesure, I've had to deal with the shoddy service of Automagic Centurion, whom I have no relationship with. My car was expected to be completed on the 15/12/2017, after several attempts to contact the service manager, I was eventually informed late Friday afternoon that my vehicle was complete however needed to go through a QC check on the 18/12/2017. I was scheduled to travel the weekend of the 16/12/2017 and had to move this out. I again attempted to get a hold of the service manager on the 16/12/2017 with no success. I placed at minimum 8 calls, left messages etc. After eventually contacting 1st for women, I was then advised that the car was still awaiting the QC, and that I should expect the vehicle on the morning of the 19/12/2017. I've attempted to get a hold of the service manager again, but was informed that he is not available. I've now had to book flights/car hire for my expected travel tomorrow as I have no indication as to when my car will be ready. This is extremely pathetic service and I cannot believe that despite me being a customer for more than 7 years, 1st for women cannot intervene.
