Calvin Klein Shoes Heel Wore Down and Faded Quickly

On September 1, I ordered a black pair of Calvin Klein shoes through Boyner’s online store. Although I have only worn the shoes a few times since receiving them, the heel area has become significantly worn and the color has noticeably faded within a very short period of time. Considering how quickly the shoes became damaged despite such limited use, as well as the amount I paid for them, I do not consider this acceptable.
I submitted a return request through Boyner, but I request that the shoes, which developed these problems after such a short period of use, be evaluated as a defective product and that an appropriate solution be provided. I will also attach a photo showing the current condition of the product to my complaint. If necessary, I request that the shoes be inspected and that I be assisted with a return or replacement of the product.
