Extremely Poor Service

My Golf 7 which has only done 50 000KMs has been with the Midrand dealership for a gearbox repair for longer than a month and no one is able to tell me when i can have my car back.<br> I keep getting the run around from the Customer Interaction center with my call being sent to different consultants for resolution every time. So far I have spoken to Liezel, Lesinda, Rolandi, David and Kevin. Now I've been told that someone else is looking into my complaint. <br> I am extremely disappointed by the poor service that i have received from VW over the past month or so. The service advisor in Midrand(Shaun) told me that my car would be ready last week wednesday(30th March) but i had to call him on Monday(4th April), still having not received the car to enquire on the progress of my car. It was then that he told me that he had received a faulty part from the warehouse in PE and had to send it back to be replaced. Why did he not call me on wednesday to tell me this? Why does VW keep faulty parts in their stock? What guarantee do i have that the new one will not be faulty? How can i ever feel safe in this car again? How can I trust VW as a brand again especially after all the recent bad publicity?
