How do I link my Xbox account to my new EA account

As the title says I need help linking my accounts. My Xbox account was apparently linked to an EA account that was set up with an old email. I cannot get into. I tried to log into that EA account and link my twitch to get a BF6 beta code but it said that again this EA account was linked to a twitch account already. I was told I couldn’t add a new twitch account so I decided to make a new EA account with my new email. I was able to link my new EA account and twitch but now I cannot link my EA account with Xbox as it says that my Xbox account is already linked to my old Ea account even though I went in there and unlinked it. Now I’m stuck in limbo with a new account I cannot link my Xbox to. And this website has been no help running my in circles. I just need to talk to a live representative
