Pull&Bear Bag Started Peeling After Short-Term Use

I purchased a black bag from the Pull&Bear store at Hilltown Mall in Izmir, and the surface of the bag began peeling after a short period of time. Even though I used the bag carefully, I was disappointed to see it become damaged and deteriorate like this.

When I went to the store to have the product inspected and request an exchange, the staff refused to assist me because I did not have my receipt with me. As soon as I mentioned that I did not have the receipt, I was also met with a rude and dismissive attitude. Even though the tags are still attached to the product and the brand is clearly visible, I do not think it is acceptable to refuse assistance solely because I did not have the receipt, especially while speaking to me in such an unpleasant manner.

I believe the peeling and deterioration of the bag may be due to a manufacturing defect, and I request that the product be inspected and that an exchange or another appropriate solution be provided if deemed necessary. I also request that the store management review the rude and disrespectful way I was treated as a customer.
