Hi @mars dude4
I’m sorry you have been sent in circles, especially when your Minecraft purchase is tied to this account.
Since the Sign-in Helper detects the account as blocked, but the password-reset page will not accept the username, use Contact Microsoft Support and tell the support advocate specifically that your username has stopped working. If necessary, access the support page using another Microsoft account.
Please keep your Minecraft purchase receipt, order number, previous account aliases, and gamertag available, but provide them only through the private support session, not in this public thread.
Unfortunately, this is a public user-to-user forum, so no one here can unlock the account, access its records, restore the Minecraft purchase, or arrange a direct callback. Support may investigate the account’s status, but agents are not permitted to manually change account details or bypass the ownership-verification process.
I understand this is not the resolution you wanted, but there are no further account-level actions that can be performed through the forum. Thank you for your understanding.
