Hey FullNaOnlli,
Unfortunately, we can't unlink your accounts here on EA Forums, as we don't have visibility into the account side of things.
However, have you already tried the steps in this guide to unlink your accounts? There are some limitations; please check the guide.
If you can't unlink the account, please follow this guide to troubleshoot the issue. If nothing works, it will be necessary to get in touch with our live support team. There's a Contact Us button at the bottom of the guide.
Our Advisors will do their best to help you! Thank you!
