Contacting EA support over Steam account linked to @disabled.ea.com

Hi! I opened a thread few days ago about a trouble I'm having with my EA account:

"HI! I recently purchased FIFA 25 through Steam. After installing and launching, I couldn't set up my EA ID because it says that my Steam account is already linked to a "@disabled.ea.com" domain.

After doing some research (I purchased the game half a week ago), I remembered that I purchased Jedi Fallen Order a few years ago, so it may be the cause of the problem with the domain.
Either way, I need to unlink whatever account is currently linked to my Steam so I can link my current account and... (sighs) play the game.

Please any guy from support reach me out to send you whatever info you may need to proceed on this. 

ps: EA Help is hilariously bad for a gaming company like yours, please improve that and put REAL people on. I had to make a post on this forum because my tickets weren't replied, the one sent by email hasn't got any answers and now I can't contact an advisor anymore through that platform."

The CM, which I'm grateful for his help, didn't read the whole thing and recommended me to contact someone through live chat, which I can't because the option simply dissapeared, as I said in the original post.

I can't contact them through the page, I also couldn't contact them while logged out and my email sent also has no response.

So... my question now is how do I contact the "support team" when I simply don't have the option anymore to do so.
I opened a new thread since CM thought his recommendation over a thing that I previously say I can't do is markable as "Solution"
