Minecraft Password Suddenly Changed and I have no way of recovering my Email and Password

A long time ago I had visited my good friends house and he was way older than me, but he had gotten on his computer and opened minecraft. Me being the yute I was, I was fascinated as all I've ever been introduced to was Xbox minecraft. He was showing me this Chinese themed town he and his friends had built. I had begged my mother to buy me minecraft and when we returned home, the day after she had done so. We bought minecraft on her newly formed account (to my knowledge). I now had a minecraft account named "onursplace" which is the origin of my nickname "onurs" which is still being used as my regular nickname till this very day. I have had this account for around probably 8-9 years when I had created it with my mother. The origin story on how the name even came to be was when we were creating the minecraft account, my mother had interjected that there was a text box to name my first world and as I was young at the time, I hadn't known what to name it so she had decided to call the world "onursplace" which actually turned out to be the name of the minecraft user itself and not a world. I have been playing minecraft consistently and frequently throughout the duration of the purchase. At the time I hadn't had an email so we had used my mothers, however over the course of years things have changed and many emails and numbers have been changed. I one day had installed a new Jedi lightsaber mod and intended to test it out to see it ingame and my launcher had been set to the login page. I had typed in the very same password and email that I've always typed for my minecraft Java account log in, however this time it was invalid. Invalid, invalid, invalid consistently had been popping up. I had spent time to contact customer support, but I was to no avail. I cannot fathom in the farthest corner of my memory, nor can my mother, of what the password to the email itself could have been. I have no way of signing into this old email account to have a password reset, so I had tried to use the recovery email which presumably would have been my fathers. Yet again we strike to no avail in him remembering the password let alone the full email. I had tried to submit 3 request tickets on microsoft forums to have the account, however I was deemed "untrustworthy" and I yet again have come to another blockade. I have recordings dating years back of me on this account to prove I have some authenticity of being the true owner. Still now I cannot find or talk to any direct customer support spokesperson so I might as well write my problem here. I have no way of remembering the original password to my email nor the recoveries, I was deemed fraudulent to receive ownership to the email, and I cannot find customer service that helps me with my problem.
