Xiaomi Poco X3 Pro Technical Issues and Frustrating Customer Service

I own a black Xiaomi Poco X3 Pro 128GB. I've been using it for two months and have encountered a number of problems. The NFC sensor did not operate from the start. The earpiece sensor failed after 15-20 days, followed by the microphone. The phone frequently freezes on the home screen and resets after around 1 or 1.5 hours, which irritates me. To add to the list, the phone's loudness changes at random when I'm using it. All of these issues have been recorded with video evidence for technical support. I sent my phone to the MI repair center in Antalya Lara on February 8, 2023. When I contacted Xiaomi Turkey, however, they did not provide any updates and were unresponsive. I became so dissatisfied that I contacted the Istanbul Evafon support department, but despite my complaint, I received no updates. Their unhelpful advice was to file a formal complaint. The true annoyance came when the Istanbul Evafon service guy contacted later to say my phone had been repaired. I stated unequivocally that I do not want repairs on a phone that is only two months old and costs 15,000 TL. I asked if they wanted repairs done on their brand-new phone, and they said yes. They insisted that I use the phone until it was repaired. I, on the other hand, declined to accept a repair for a high-value, rarely-used equipment. My message to Xiaomi Turkey is to provide a solution rather than an irritating workaround.
