So my ex got me banned 'cause I had he made me do bad stuff and can you please unban me?...

The enforcement team does not use the forums. You would have to check the enforcement site to see about submitting a case review. https://support.xbox.com/en-US/help/family-online-safety/enforcement/how-to-submit-a-case-review

okay so you want to call me a liar. ever heard of other people i the party and yes he got banned but he filed out the questionnaire and got unbanned regardless the time frame the fact he got unbanned on the same day he got banned bad to be honest . again
regardless the time frame

someone went on my account his name is [Mod Removed] he banned my account an I went to chat support an spoke to angeli an she told me to come here cause you guys will unban me as I was saying he went on my acc an started swearing at other
accounts and modding on it an I got all the blame an I had all my favourite games on it were I have to start again unless you unban me please?

UNBAN ME I HAVE NOT VIOLATED THE CODE OF CONDUCT YOU CAN BAN ME FOR A COUPLE OF DAYS BUT WHY PERMANENTLY THE REAL HACKERS ARE OUT THERE AND YOU ARE PICKING ON THE NON HACKERS YOU GOT SOME NERVES I WILL GIVE YOU THAT AT LEAST LET RETRIEVE MY LOST STUFF OR
DO YOU NOT CARE! PLEASE UNBAN ME I DO NOT MEAN TO SOUND RUDE BUT SUMMER IS THE ONLY TIME I CAN PLAY SINCE I HAVE STUDYING.

Submitting an appeal would be the only way to possibly fix it. If the enforcement team denied the appeal, there is nothing else that can be done.

Can y'all please unbanned me my friend had my account in his Xbox and text him stuff that would get me ban pls unbanned me
