Can't unlink my steam from Old EA account

So I have 2 EA accounts, one is very old, and the somewhat newer one is my main. My older one has my steam account linked and when unlinking it, it does nothing, it stays on the account. Has anyone had this problem? I'm trying to contact EA support but they make it so difficult to simply send and email without going through tons of categories, and sections of FAQs and forums.

One simple task and I can't do it. HELP
