Calvin Klein Sneakers Wore Out In Just 4 Months

I experienced serious quality issues with a pair of Calvin Klein sneakers I purchased about 8 months ago for ₺3,500. Even though I did not wear them regularly, within just 4 months the outsole developed holes in two different places, and the sole completely detached, forcing me to buy a new one. I was also very disappointed with the stitching coming apart and the overall poor material quality. I bought the product from the Mall of Istanbul Forum store, but since I lost my receipt, the store refused to take any action. However, it is unacceptable for shoes at this price to deteriorate so quickly. I will also attach photos as proof. I am requesting a replacement, repair, or refund for the product and want my grievance resolved.
