Samsung S22 Ultra Suddenly Dead, Not Turning On

I purchased a Samsung S22 Ultra phone as an original product and have been using it carefully for about three years. My phone has never been dropped, hit or damaged in any way, yet it suddenly stopped working and no longer turns on. I find it unacceptable that a phone that has been used so carefully and has not suffered any impact suddenly develops such a serious fault. During the warranty period, I had already experienced various problems with this device and sent it to technical service twice. After the examinations at that time, they accepted that I was right and the battery was replaced. However, after a few months, despite this battery replacement, my phone has now completely stopped turning on. This situation leads me to think that either a poor-quality battery was installed, or the device was damaged in some way during the previous repair. In both cases, I believe that the fault is not due to my usage, but is related to the product or the service provided. With this latest fault, I contacted Samsung technical service and customer service again. Despite the history of repeated faults and previous interventions, they told me that the device is now out of warranty and demanded a high repair fee. I was not offered any support or goodwill solution, and I felt that my complaint was dismissed rather than being genuinely dealt with. My request is that this fault, which I consider to be a chronic and hidden defect, be resolved without charging me a high repair fee, and that a fair solution such as free or reasonably priced repair, or if necessary, a device replacement be offered. I expect Samsung to recognize that this situation is not due to user error, but to the product and service quality, and to support me accordingly.
