Refusal of Warranty Coverage for Arçelik

I own an Arçelik brand 9120TMX model washing machine whose warranty period is still ongoing. The bellows (door gasket) of this machine tore today without any impact or intervention on my part. The authorized service in Şanlıurfa, without even examining the situation in detail, directly claimed that it was user error and demanded a repair fee of ₺4,000, which I find extremely exorbitant. The tear did not occur due to a sharp or cutting object; it is clearly due to material fatigue and poor production quality, as can be seen from the condition of the gasket. Although I called the Arçelik headquarters about the issue and had a complaint record created, the feedback I received did not resolve my grievance and only offered excuses. Even a reasonable discount that should have been provided under customer satisfaction was refused, and no facilitation was offered, despite the product still being under warranty. I do not accept that no support is provided and that such excessive costs are imposed on the consumer for a product under warranty. I request that my grievance be resolved urgently and that the torn bellows be replaced free of charge within the scope of the warranty and customer satisfaction. Otherwise, I state that I will exercise my legal rights and apply to the Consumer Arbitration Committee (THH) with the call recordings and service report.
