I can’t access my old hotmail account!

I think my account got hacked, and I'm trying to reset the password, I never changed the password myself personally, but one day I tried to log on to it and the password was changed, I thought no more of it and just made a new one because I wasn't fond of the email address anyway. I made this account when I was about 11, so I must have lied about my age (I know I shouldn't have done that), I also never used this address for emails and I never made any extra folders, so that rules out the form way of getting my email back. I also don't have access to the phone number that I used for this account, or the alternative email so I can't get a reset link! This is particularly annoying because it means I'm locked out of my Xbox live account due their new proofs thing, and if I stay locked out I've essentially wasted a third of the sixty euro I spent on my yearly membership, not to mind all my save games I won't be able to access.
