Lost all my Minecraft account details, how to fix this?

Ok so i haven t played Minecraft in a VERY long time. I can t recall if it s been years or months, oh well. Anyway i tried logging into my account today called xXPixelHeartXx. Turns out i have no idea what the password is and the e-mail linked to my account is deleted. I dont even remember my Mojang details… I tried making a new one but wont let me login. So what do i do?
Added (1). I remember the e-mail used but it has been deleted so i have no idea how to reset the password
Added (2). Nevermind, i have sent a request to change the e-mail and password as i can prove the account is mine with the purchase code. Thanks for the help anyway:)
