Samsung S25 Ultra Service Report Contradicted by Working Device

I am using a Samsung S25 Ultra phone, which is under Turkey distributor warranty and has an invoice, and I delivered my device to the authorized service due to a camera malfunction. The process took place between 23–26 May at the authorized service point named Ebru İletişim in Bursa, Osmangazi, and the service record number for my device is 4294482146. During the service process, I was first informed that the device had been opened and would be delivered to me in a short time. Afterwards, without obtaining any written or verbal approval from me, I was told that the battery would be replaced, although I was not asked for any consent for this planned operation. Later in the process, I was informed by the service that the device could not be set up, that there was a software problem and that a paid procedure was required. At the beginning, I was told that an amount of approximately ₺4,400 would be charged for this procedure. However, when I went to pick up the device, I was informed that this amount had been increased to approximately ₺41,000. Upon this situation, I took back my device from the service without having any repair or paid procedure done. Contrary to the service’s statements that the device “cannot be set up” and “cannot be used”, after I received my phone I set it up myself without any technical support and I continue to use it actively without any problem. I am even writing this complaint text from the same device. For these reasons, I request that the reasons for the operations planned without my approval be clearly explained, that the technical and legal grounds for the difference between the initially stated amount and the later extremely high amount be presented, that it be clarified on which examination and report the technical finding of “the device cannot be set up” was based, and that it be justified why a fee close to the device’s value was demanded for a device delivered solely due to a camera malfunction. I also request that the necessary investigation be carried out regarding the victimization I experienced and that I be provided with a written response. If I do not receive a satisfactory response, I state that I will exercise my legal rights before the Consumer Arbitration Committee and the relevant authorities, together with all service records, service reports and other documents related to this process.
