Apex merged two separate (and paid for) accounts into a single account!

Me and my brother play Apex on our individual consoles.

Apparently his PSN got tagged to the EA account linked to my PS5 when he logged in on my system to try the PS5 when it came out.

We tried to unlink it but EA doesn't have an unlink button for PSN accounts.

Now with the cross progression merge, all our stuff has moved to a single account and only one of us can play. 

This is pretty stupid, given we were both recently active on each individual account AND we've paid for battle passes on each of the accounts. Not to mention the 15k hours we've put into the game since it came out in 2016. 

Added a screenshot where you can see I'm not allowed to unlink my brother's PSN from my EA account.

We need our accounts back EA!
