Hi 청현 박,
Welcome to the Microsoft Q&A forum.
Minecraft purchases are refunded by the store where the game was purchased, and the refund decision is handled by the selling platform (for example, Microsoft Store, Google Play, or Apple App Store).
Please check where Minecraft was purchased, look at your receipt or Kakao Pay transaction details to confirm the store (e.g., Microsoft Store, Google Play, or Apple). Then you can request a refund from that store.
Here's the official policy reference that might be helpful to you: Request a Minecraft Refund
Please note that refund eligibility can depend on factors such as how much time has passed since purchase and whether the game or content has already been used or downloaded. Subscription products may have different refund conditions.
I hope this helps clarify the process and makes the next steps easier. Please feel free to reach out again if you need further assistance. Thanks for your effort.
