Xiaomi Mi Band 6 Broken Screen and a Costly Upgrade!

Hepsiburada sold me a Xiaomi Mi Band 6 wristband. The screen became loose during the warranty period. I sent it to the authorized service provider, Sanalbt, who replaced it with a new one. However, the screen became loose again after only a year. When I called the service center, they told me that the warranty had expired based on the invoice date, but that they would still evaluate it under warranty terms. As a result, I sent the product to the service center at my own expense, including shipping. After informing me that they couldn't repair it, the service center suggested sending me a Mi Band 7 for an additional 1000 TL after deducting the invoice amount. The Mi Band 7 is 850 TL on Hepsiburada, so I'm perplexed by their request for an additional 1000 TL. These products clearly have a one-year lifespan. They only take into account the time spent at the service center for warranty evaluation and disregard shipping times. Why did they ask me to send it in for warranty evaluation if they had no intention of repairing it? This is my first Xiaomi purchase, and it will undoubtedly be my last. I will not make this mistake again.
