WMF Quality One Cookware Set Showed Fading And Wear After Minimal Use

I purchased the WMF Quality One 5-piece cookware set for my dowry. I recently started using the products, and even though I haven’t used them frequently, fading has appeared on the interior surfaces and around the edges of the pots. It is disappointing that the products show this kind of deterioration in such a short time.

I have the receipt and warranty documents. I request a replacement for my product.
