If i unlink my ea account to playstation account .. can i relink it again

You can unlink your platform accounts from your EA Account if you want to link them to a different EA Account, as long as your EA Account has never had the same account type linked to it before.

Today I wanted to use the EA play games on my ps4. I thought that instead of paying to use it on my ps4 i could link my ea account with ea play membership to use the games. When I went to do that, another ea account that I forgot about turned out to be linked to my psn. I logged in and I unlinked the psn account. I followed the instructions on the ea help website to link my account. When I did that I was not able to chose which ea account I wanted to link it to. Is there another way to chose which account or can I delete my old account that I dont want to use. Please help me.
