Damaged rims after tyre change – 18 inch

Hello dear Kia municipality, I had to notice yesterday at the rim cleaning unfortunately that my rims (original Kia 18 inches) are scratched in the area of the rim nuts. I suspect that my workshop caused this damage last week when changing from winter to summer tires. The rims were definitely free of scratches and damage before the change. Have an appointment with my dealer tomorrow and have already opened the coffee. Has any of you at the 18 inch Kia Rims had similar experiences? (Had previously driven an Astra K with 18 inch rims 3 years ago and there was never anything damaged).
