How do I get my Minecraft account back?


How do I get my Minecraft account back?

I played Minecraft years ago, when I had an old gmail email. I deleted that account awhile ago and I want to play Minecraft again.

I've forgotten my password and my email is not certain, as my brother may have changed both.

Basically I don't know my email or password but I have a good idea what the username is and what the email probably is but I no longer have access to it.

Am I screwed? I emailed support a month ago but they haven't responded which is ridiculous.

I really don't want to buy the game all over again.

What do I need to recover my Minecraft account? Do I need transaction IDs from purchases, if so can I find those without my email?
