I feel for you fizzking, Sometimes things like this do happen. That said, if this happened to my car id be fuming. lol.. When my car is being serviced i usually sit near the window and see what it being done. The dealers have put a note on my account to not Wash the vehicle or to rotate the wheels. I usually wash the car myself or more then likely take it to the carwash.. With the Rotations, ive been taking it to Brigestone tyre centre who rotate the wheels for free as i have purchased 4 tyres from them earlier this year.... One other thing i would do if i was in your place is to call the dealer and speak to the Service Manager, 99% of the time you will get results... Its worth a shot :)
