Help recovering stolen minecraft account.

Hello, around june/july, my minecraft account was stolen. My microsoft account happened to vanish when that happened, I am not sure exactly how. But it did, and I ended up making another one with the email address I am using right now to send this message and also this was the email address for my Minecraft account and old Microsoft account. Please let me know what I can do to get my account back. You should know I am pretty sure I had actually migrated by account to my microsoft account

:)
