I Face JBL 720BT Hinge Breaking and Warranty Denial for a Known Defect

I purchased a JBL 720BT over-ear Bluetooth headset through Trendyol, and about a week ago, the right hinge connection of the headphones broke. I sent the product to the authorized service under warranty. Even though this is a widely reported and chronic issue experienced by many users of this model, the service labeled the problem as “user damage” and, instead of offering a solution under warranty, attempted to sell me a new product.

No repair was performed on my headphones, and I was not given any clear or convincing explanation as to why a known structural hinge failure is being treated as user-caused damage. I also tried to contact JBL customer service, but I was unable to reach anyone through their customer support channels.

I request that the hinge breakage on my JBL 720BT be re-evaluated under warranty as a manufacturing or structural defect, and that my product be repaired free of charge, or replaced with a new unit if repair is not possible. I expect this issue to be handled without shifting responsibility onto the user for a known design flaw and without forcing me to purchase a new product.
