Linking issues

Hello my name is [SU edit - removed] and I play apex legends. I used to have an old apex legends account on my old Xbox with a ton of value and items on it. I now play on PlayStation 5 and am on a new account because of this, when I went to link the Xbox account to the PlayStation account through ea I accidentally linked it to the wrong PlayStation account meaning that I am unable to link it to another PlayStation account in its lifetime. Please help me so that I can link the accounts correctly
