Nike Tracksuit Developed Thread Pulls Shortly After Purchase

I purchased a pair of Nike sweatpants from the Metropol Boyner store and, within about one month of normal use, I noticed intermittent thread pulling in different areas of the fabric. This problem occurred despite me using the product under normal conditions and taking care of it properly, which led me to believe there is a quality defect. After noticing the issue, I took the sweatpants back to the Metropol Boyner store and requested a product exchange. However, my request was rejected, and the change was not approved, even though the defect appeared in a very short period and is clearly not due to heavy or improper use. I kindly request that the defective Nike sweatpants I purchased from Metropol Boyner be exchanged with a new, fault-free product as soon as possible. I expect this manufacturing defect to be reassessed and my consumer rights to be taken into consideration.
