Problem with banned EA account linked to Steam blocking Apex Legends gameplay

Hi, I have a serious problem. My EA account got banned but it’s still linked to my main Steam account, which prevents me from playing Apex Legends on Steam.

I’ve contacted EA support multiple times but nothing moves forward. I want someone to help me unlink this banned account or advise how to fix this, because it’s super frustrating.

Has anyone experienced the same or knows how to bypass this?

Thanks in advance for any help!
