how do i link my ea account to my apex legends on ps4?

same issue, basically i know the EA account linked to my PS4 account for my Apex Legends; however, I forgot the password & the e-mail service still isnt working, so being eager to claim my twitch prime loot; I just linked it to a different EA anyways with the belief I could switch it in game, but this ended up not being true.  I don’t want to have to make a new account just to claim my twitch prime & lose all my stats. hoping they’ll add a feature or a website, something to swap the EA account associated with consoles, and pc’s.       i was disappointed because i just claimed it on an EA account that’s not even on my main, or any PlayStation account; even.  😭   sadddd.  really looking at it, there’s not much they can do for my problem; I don’t know why the email isn’t being sent to me, sucks.
