Apple Service Lost May Case

I purchased an original iPhone 15 case, but within a short time it experienced severe deformation. The case literally started to crumble piece by piece, took on a look as if it had been taken out of the trash, and this completely ruined both the comfort of use and the appearance of the product. Due to this problem, I took the product to the Apple authorized service provider Gürgençler and handed it over to them, and a technical service product form was issued in my name. They requested the invoice, I submitted it, and then I sent a follow‑up e‑mail to remind them of the situation. I sent my last email on 25 July at 14:56, but despite the time that has passed, I have not received any response. In addition, the authorized private service has lost the case, which I believe is one of the reasons why they are not getting back to me. Although this is an original Apple product, the case has reached this condition in a very short time, and on top of that the authorized service has lost the product and failed to respond. I kindly request that Apple carry out the necessary examination, ensure that my grievance is resolved, and that the product is either replaced or the price is refunded, and that the situation at the Gürgençler authorized service is investigated and clarified.
