Vestel Windsor AC Fails to Cool After Repeated Repairs by Authorized Service

My Vestel brand Windsor inverter 18 A++ R32 wall-mounted split air conditioner has been sent to the authorized service center twice for the exact same fault. Each time, I was told the unit was repaired, and it was reinstalled in my home, but the device still does not cool, and my problem remains completely unresolved.

My first service request was on July 3, 2025, and my second was on July 22, 2026. During both visits, the team from authorized service center Akal Beyaz Eşya Day. Tük. Mall. Serv. Hiz. San. Ve tic. Ltd. Şti. failed to resolve the issue and also caused damage to my home. They dirtied and ruined my newly painted walls, and I also observed them employing a 15-year-old child on their crew. I have experienced severe hardship due to both the quality of service and their conduct.

Despite the same defect recurring twice and the air conditioner still failing to cool, no permanent solution has been offered. Therefore, I demand a complete replacement with a new unit rather than another repair attempt. I request that the process be concluded quickly in favor of customer satisfaction, taking into account the hardship I experienced and the damage caused to my home.
