My account was deleted or stolen by malware witthout my knowledge

Hello Microsoft Support Team, my original Microsoft account appears to have been either deleted or stolen without my knowledge. When I tried signing in today, I received an error stating that an account with my email address does not exist. I want to clarify that I did not receive any emails about suspicious activity, password changes, or account inactivity. I still have proof of ownership (including purchase receipts, if activating free minecraft capes counts as purchase, and previous correspondence), but unfortunately, the account recovery form doesn’t allow me to upload images or documents to verify my identity. The account in question used the same email address and username as the one I’m messaging from now, since I thought that creating same account would fix everything. Since I’ve had to create a new Microsoft account using the same email and the old one seems to be gone, I’m kindly asking if it’s possible to recover my original account or at least transfer the Minecraft purchase to this newly created account.

1. Please let me know:Whether my old account was permanently deleted or possibly compromised.
2. If there’s a way to submit my documentation or proof of ownership to assist in verifying my claim.
3. Whether my Minecraft purchase can be restored or transferred to this account if recovery isn’t possible.

Thank you for your time and help with this matter. I just want to recover access to what I legitimately own. I attached one of the screenshots that can be proof that this account is mine (I can uncensor it)
