Hello oskar Frąckowiak,
I'm sorry to hear the coins didn't show up. Usually, it comes down to one of two things.
The most likely cause is an accidental account mismatch. If the code was (mistakenly) redeemed on a different account than the one signed into Minecraft, then of course the coins won't appear. To check, open Minecraft > Settings > Account and confirm which Microsoft account is active, then make sure it matches the account you used to redeem at https://redeem.microsoft.com.
If the accounts match, it may just be a sync delay — coins can occasionally take up to 24–48 hours to reflect. Try restarting Minecraft and checking again after some time.
If neither resolves it, contact Microsoft Support directly with your redemption confirmation and they can look into it: https://support.microsoft.com.
