Happened to me as well. Went in for a minor center console adjustment and saw them work on my car.
2 techs moved the front seats all the way back lying belly down on my Model S' door sills. As I looked closely, both techs were wearing utility belts with tools hanging from them. Needless to say, both door sills got scratched. The passenger side got heavy scuff marks that were immediately polished off when I highlighted the damage. The driver's side got a deep 1 inch long scratch that took some paint off.
As they finished polishing the passenger side, they regrettably informed me that they didn't have any Obsidian Black Metallic paint in stock in order to touch-up the scratch, just regular black paint, "but they didn't recommend using regular black, as it would not match my metallic paint"...
I ran out of there and dropped my Model S with my detailer who installed the PPF and ceramic coat on my car, who showed me he even had the OEM Tesla
paint repair kits. Went back to the service center with my detailer's invoice and fortunately they refunded the full cost.
Moral of the story, do fight this
@Fragel77 and let us know how it goes.
