i lost my email and cant get into my account for minecraft

I tried to add my other email to my microsoft account but it says its part of a reserved domain, So i cant add it as an alternative account. So another minecraft player is using my email for their minecraft earth account and thats why i cant use it? When
i sign into minecraft earth i come up as princess.cossign which isnt me but when i play on normal minecraft everything is fine, why is there a problem all of a sudden because of playing minecraft earth? Id like to be able to use my main minecraft account on
minecraft earth and not have it come up as someone i dont knows minecraft account. I dont want my email connected to another minecraft account and i also feel bad for the the other person that they might have lost access to their account because of this mix
up or whatever it is, im so confused... please help!?

I have more information over the hack. The code was a reset password email where they were able to migrate my minecraft account under their email. That's when i lost it. i contacted support there is nothing i can and i cant seem to get anyone on the phone. Hundreds of dollars down the drain

Yes I lost my email and password to the account, but I have the transaction ID of when I bought the minecraft account.

Hi I have recently lost access to my gamertag on minecraft due to changing my password for my emails is there a way of recovering that account ?
