I got it to work!
I had 2 Xbox accounts linked to my ea account. As many have written an old Xbox360 account and a newer one to the same email. Here's the chat:
John (2021-04-06 08:59:01): Thank you for contacting EA HELP, my name is John, may I start with your first name please?
(2021-04-06 08:59:43): Hi, My name is ------.
John (2021-04-06 08:59:53): Nice to meet you, -------.
John (2021-04-06 09:00:09): I can see that you have contacted us for the Xbox game pass. Could you tell me more about it?
(2021-04-06 09:02:13): I contacted you a few weeks ago with a problem with account linking from xbox gamepass to EA play. where it says that I allready have a gametag linked. You told me then that it was a problem that was known and you were going to fix it, but nothing has changed what I can see. I have been to my account settings and linked accounts on the EA site and I do have 2 accounts to xbox. But surely you could delete 1 of them so I can play your games?
John (2021-04-06 09:03:54): Yes. Let me look in the EA account and I will surely help you to un-link one Gamertag for accessing the EA play via Game pass. No worries.
John (2021-04-06 09:03:57): May I ask few questions in order to locate your account?
(2021-04-06 09:04:20): sure
John (2021-04-06 09:04:41): Can you please share the registered email address and Gamertag with me?
(2021-04-06 09:05:34): ********@*******.com - ********
(2021-04-06 09:06:10): connected accounts are Xbox------ & XXXXXXX + Steam - *******
(2021-04-06 09:06:43): Im playing exclusivly on Xbox- ------ so I would like to unlink XXXXXX
John (2021-04-06 09:06:54): Which Gamertag you wish to remove?
(2021-04-06 09:06:58): XXXXXX
John (2021-04-06 09:08:11): Please read the disclaimer carefully and accept.
John (2021-04-06 09:08:15): When we unlink a platform account from your account, you will be able to link that platform account to another EA Account, but your in-game progress will not transfer over. That means you’ll lose access to all entitlements, games, memberships or subscriptions, and in-game purchases that are associated with that platform account. You will also permanently lose all game progress. If we unlink a platform account you use to play FIFA, and that platform account is still set as active in the Web or Companion App, you will lose access to those apps entirely on your account. If we unlink a platform account you use to play Apex Legends, you may have issues with Battle Pass leveling, item unlocks, and other errors.
Once you unlink a platform account from your EA Account and link it to another, you won’t be able to unlink it again for six months. You also will not be able to link it to an EA Account that has already had the same type of account linked to it before, even if there isn’t one currently linked. That means if you’ve had an Xbox account linked to your EA Account in the past, you can’t link a different Xbox account to it in the future.
Can you confirm that you would still like to have the platform account unlinked from your EA Account?
(2021-04-06 09:09:06): Yes i would like that
John (2021-04-06 09:09:20): Thanks. Would you mind holding for a couple of minutes while I fetch some relevant information?
(2021-04-06 09:09:28): yep
John (2021-04-06 09:12:37): Thanks for the wait. By the way how are you and how is your day going?
(2021-04-06 09:13:23): Its good ^^ woke up about an hour ago, gonna get me some breakfast soon
John (2021-04-06 09:14:25): It is done.
John (2021-04-06 09:14:43): You can also unlink platform account using this EA Help article.

John (2021-04-06 09:17:05): Glad to help you out. Is there anything else I may assist you with today?
(2021-04-06 09:17:16): YES IT WORKS! Thank you very much
(2021-04-06 09:18:16): no ty that did the trick
John (2021-04-06 09:18:20): You are most welcome. Glad to help you out. Is there anything else I may assist you with today?
After this conversation my old user was gone from EA, and I restarted Xbox & Ea desktop and it worked! THey can actually help :D
Yeah except that's a different issue. You were one of the lucky ones that somehow got two Xbox accounts attached to one EA account. If you had one Xbox account attached and wanted to detach it, then attach a new one, you are SOL. Their official position thus far has been: "This is our policy, we've sent your concerns to wherever, you can always create a new EA account and attach it but you will not have access all of your purchased games, progress, and friends list. Good luck sucker".
So I'm glad they were able to help you with two Xbox accounts being linked at the same time, but with my (and many others') problem of wanting to link a new Xbox account after unlinking an old unused one there is no actual solution.
