Poor service by Audi Service Centre

I have taken a car for 120000 a service at Audi Centre Centurion in January 2018. When the car came back, the right bulb was not working. I then contacted the dealership and was told to bring the car so that they can check it. After that they told me that the problem is the bulb. They replaced the right bulb at a cost of around R4500.

At 135000 km, I took my car for service at Audi East rand. The car was serviced and came back with no problem.

At 150000 km I took my car for service at Audi Centre Bruma. It came back with the same problem of the right bulb. I then contacted the dealer and was told to bring the car for check-up but I will pay. When I took my car in for service, it was fine with no problems at all.

Now I am even scared to take the car to Audi again. I now question the quality of work or the parts that are being sold. How can a bulb of 6 months die like that?
