Bad service at Audi

Took my car in for service and to change driver's door lock. I asked them to change driver's door lock. They changed 2 other doors bit not drivers door! despite me having to keave my car an extra day at the dealership so they could change the locks.. Secondly, when making the booking, I had to provide my full personal information before I could book car....very unusual when I compare to other Audi dealerships. Surely tgey shlukd have a centralised system so that they could determine if one can meet the costs of the service.
