EA Account Link to Xbox Screwed CFB 26 Online Dynasty

My brother has an EA account linked to his xbox account (we used to share). We used to share an EA account as kids and our old account (now his) is linked there- or was... I unlinked it in an effort to set my own xbox account to it and make it my EA account as he had one. Well, it turns out my Xbox account was linked to an account with an old email I do not use. I was able to get in. I unlinked my brothers xbox account, in doing so I thought I would link mine, so I unlinked mine as well. Turns out an EA account can only have one xbox account linked to it for its lifetime. I did not know this. I ended up making a brand new EA account and linking my xbox to that. Somehow my brother had an account and his xbox gamertag was linked to his and our childhood account. HOW? Well, the devastating this is that it has removed us from our online dynasty with friends on CFB 26. We have tried to rejoin, but our teams are taken but unnamed users. They are not on the members tab, but when you try to select a new team they are not selectable. Is there a way to merge our EA accounts and get back into our dynasty? Is there a way to remove the users from the league (my brother was the owner, so now there are 4 commish, but they are unable to do anything). Are there any solutions to getting us back into our beloved dynasty?! All of this for the BF6 beta and I can't even play it. Really crappy issue just trying to clean up accounts and play the beta. EA HELP ME.
