cant unlink xbox account of 5 years

I'm suspended for no reason! I would like to object to the sanctions. After a long day at work, I played Apex at home as usual. I play Apex to relax in my spare time. You can reduce a lot of stress in the game! As a gamer. I think apex is the most competitive and interesting game right now. Of course I loved it, but suddenly it was banned! I feel weird about sanctions because I never break the rules. After the ban was imposed, I checked your rules to determine if anything inappropriate had been done. I read the rules and I don't think I broke your rules! No cheating, no hate speech, no third-party software, no party cheats! I always play this game alone, but my account check found that I was illegally logged in by someone else and kept logging in in the early hours of the morning, so there must have been an accidental mistake. I hope you can help me find out the reason.
