FC26 and unlinked EA account

Hey 67Wally​ sorry to see that your son is in such a situation regarding his account.

If you have unlinked the account and then relinked it and are seeing a message that you must wait 6 months, then I'm sorry to say, but there is no one at EA who can speed this up.

Likewise, we also would not be able to transfer content between accounts; all the risks of linking and unlinking an account are called out in the help article here

When you unlink a platform account from your EA Account, you can link it to another EA Account, but your game progress won’t transfer over.That means you’ll permanently lose access to: 

• game progress
• DLC, expansions, and anything extra you have for your game
• memberships and subscriptions
• previous drops and other rewards
• in-game purchases.

The only thing I can recommend is to speak with our live support team to see what they can advise. They may have some process that they can look into to see if there is any options available for your son.
