Unable to unlink Steam account – linked to unknown/hacked EA account

Hi everyone,

I'm hoping someone can help me or point me to the right support channel.

A while ago my Steam account was compromised (hacked). During that time, whoever accessed my account linked it to an EA account that is not mine and that I have no access to or knowledge of (not my email, not my credentials).

Now I have recovered my Steam account and I also have my own legitimate EA account, but I can't link them together because:

To link my Steam account to my correct EA account, I first need to unlink Steam from the unknown EA account.

That unlinking has to be done from the EA account side, but since I don't own or have access to that EA account, I can't do it.

As a result, my Steam account stays "stuck" linked to an account that isn't mine, and I can't connect it to my real EA account.

Has anyone gone through something similar? Is there a way to request EA support to manually unlink my Steam account from that unknown EA account for security reasons. I tried to create a case several times, but although it shows an ID, no case appears in "my cases" and nobody has ever contacted me.

Any guidance on the correct process or who to contact would be greatly appreciated.

Thanks in advance!
