iPhone 15 Plus MagSafe Clear Case Turned Yellow After One Year

I bought an iPhone 15 Plus MagSafe clear case exactly a year ago, and now it has turned an unsightly yellow. The tech store I purchased it from assured me it wouldn’t discolor for at least 2-3 years, yet here I am unable to use a product I paid a significant amount for. Despite the store's promises, they refuse to offer a replacement or solution.

I feel misled and disappointed, especially since I trusted their claims about the case’s durability. This experience has left me frustrated, and I am asking Apple or the store to resolve this issue, either through a replacement or an alternative solution.
