New alloy wheels arrived scratched – and now?

Hello together I ordered 4 aluminiums with winter tires on the internet a few weeks ago and unpacked it only this weekend. As they hung on the car I noticed that every single rim had numerous scratches from the Montier machine. The most logical would be to remove the tires again, summer tires on it and exchange them. But now the assembly has cost me something, and in a few days again the same game and gets cold and so on usf. e just mounted and the company wrote that I would like to have an exchange for new rims in the local branch of the company. The answer: “Due to the assembly of the complete wheels, a rim replacement is unfortunately no longer possible. We would like to offer you a discount of 20? per rim.” I find already great that is reacted so quickly. But the scratches remain nevertheless and 2-3 years then I should have rusted rims, right? And modest looks What would you suggest to me?
