Volkswagen Constantia Kloof worst service ever

Volkswagen Constantia Kloof service is non existent. Have taken my Golf 7 Gti in to the 5 time now. First time was for a service and to replace the windshield washer water bottle, when I collected my car they advised me that I’d have to bring it back for the water bottle to be replaced. They said they’ll let me know when they have a courtesy car available I waited 2 month and they still didn’t phone me. One morning on my way to work my car gave me a msg that I should park my car and phone the dealership immediately. I phoned them and they said I should bring it in apparently there was a switch that had to be replaced on the gearbox which according to the is a normal thing and happens to most DSG gearboxes. When I got there they had no record of the water bottle that had to be replaced and I was never on the list to get a courtesy car. Collected my car the afternoon because they had to order the part and advised me that I can still drive with the car but they did replace the water bottle. As I drove out of the dealership my car was making a funny noise immediately went back and was advised that now all of a sudden my bearings needs to be replaced. The next morning when I got to my car I saw that I had a flat tyre and had one of the *****s in it that matched the *****s of the water bottle that they replaced. So it wasn’t my bearings they puncture my wheel in their workshop. A few days later I had to take my car back for the gearbox to be fixed once again they had no courtesy car available and was without a car for another 3 days. When I got my car back I saw that the silver trim around my gear lever was damaged and the paneling was not put back correctly and was still lose. I phoned them and had to take my car back again for them to take pictures of the damage. After about 4 weeks they phoned me and said I should bring my car back and come and speak to the branch manager. He advised me that this is also something that happens the silver trim around the gear lever breaks if the car is parked in the sun but they will replaced it and pay for 1/3 of the tyre that they damaged I should once again bring the car back on a later stage and that they will give me a courtesy car. Book the car to brought back the next Thursday. Phoned them on the Wednesday to confirm that I will be bringing my car in the next day and that they have a courtesy car for me. Bit was advised that they forgot and will let me know when they have a courtesy car available. It’s been 2 weeks now and still have not heard anything. They never phone back if you leave them a message and never give you feedback. If you don’t phone the you will never know whats going on. Their workshop keeps on damaging my vehicle and the staff is arrogant and not helpful. Throughout all of this they never admitted that any of this is their fault apparently it is just things that happens to their cars. Is this the type of service that Volkswagen South Africa wants their customer to receive

The reason that I need a courtesy car is that I am not office based and need my vehicle every day to work.

Never take your car for a service or any repair to Volkswagen Constantia Kloof they will probably break more stuff than fixed
