Why can't I contact an appeals team?

So I've been given a comms ban and a strike for literally no reason. I've tried to contact an agent, but when it gets to the window, it doesn't give any option to do so, just to "message the gaming community".

I've requested a callback, they looked into it and got back to me saying "there's nothing they can do to look into the account".

I've been unfairly treated here, for literally no reason (not an exaggeration, nothing offensive was said, no swear words were used. Why is it so hard to contact the right people through xbox?
