Poor Service by VW SA and German

I took my GTI polo for major service to VW Witbank. In November 2024.They did the service and informed me that they need to replace the wiring harness which needs to be ordered.. it got ordered and I paid +R8k for the spare. VW said it will take two weeks. After that 2 weeks stories started Case number ***. They kept on shifting the goal post for delivery. First VW responded to Collen the manager who internvened by promising the delivery in January 2025. Nothing happened. New date was February 2025 , nothing happened. New march 2025 nothing happen. New date 12 April , nothing happened, new date 22 April. , nothing happened. After the 12th of April I called the customer care , after a long conversation, the lady said I must send the email which got automatic acknowledgment. Nothing happen. On the 24th of April , Collen the branch manager send the WhatsApp after enquiry with new date, 26th of May.. Now almost 5 months the car is standing at VW Witbank. On the 23rd I followed up on the email with customer care, again no response except automatic acknowledgment. By any standard this VW firm is becoming unreliable international. This is not acceptable at all. The service of VW South Africa and German where they order their spare parts is pathetic. This performance is unacceptable at all standards. They are just piissing me off. According to the trend, on the 26th of May , I expect a new date. Kind Regards . AAM
