Puma Sneakers Peeled and Hurt My Feet After One Use

I bought a pair of Puma sneakers from Intersport on June 1, 2025. After wearing them for just three hours in a single day, the leather on both sides started peeling off, and although I purchased my usual size, the back of my feet were left bleeding. I was shocked by how such damage could occur after such minimal use, especially from a well-known brand like Puma. I returned to the store immediately on June 3, but it has been 10 days without a single call or message. My money has gone to waste. The staff seem to do nothing but mislead customers and sell non-genuine products. It's truly shameful. I won’t let this go and will be taking the matter to the Consumer Court.
