IKEA's Dish Stand Rusted! Doesn't Protect Its Product!

The hultarp dish rack with product code 20444435, which I bought from IKEA on 07-09-2022, rusted (Transaction Number on the invoice: 140902321). The product is sold as a dish rack and it will come into contact with water and can rust. When I took the product to the store, they said that the product was not sold as stainless, so they could not process it. They told me to contact customer service, which I did. Customer service directed me to the store again. The store said the same thing again. They made an absurd explanation that the product is not stainless steel, so it may rust. There is a quality problem with the product. If the product coating was of good quality, it would not rust again. I demanded an exchange, they refused, gave me a shopping voucher in the store up to the invoice amount. But there is almost 2 times the difference between the price I bought this product and its current price. Why am I paying for IKEA's poor-quality products? I don't understand how it can be normal for the product they sell as a dish rack to rust. There is a quality problem with the product and I demand the replacement of this product.
