Pull up the image on the configurator and take a photo or screenshot, then submit as proof of what you expected to receive, I would be arguing if I was in your situation
The factory is in shutdown until tomorrow I believe. Unless the Factory replied before Christmas, are you sure they spoke to the Factory? But you can see the logo stitching on the seat of the below if you zoom in, it’s the colour of the leather ( I have the original picture as I took it, in that the logo is clear). I do agree with your position by the way, I’d not be happy especially as the configurator shows the logo in stitching colour and has done since I did an early configuration with red stitching.
