EA Account Deletion

Hello,

I have two EA accounts, the one is linked with my platform account (PSN) and I recently unlinked the platform account to relink it with the new one. As a result, I lost all my previous in-game progress. I have to wait 6 months until I can unlink the PSN account again.

i would like to know if I ask EA support to delete my current EA account, will all linked platform accounts (including the PSN account) be automatically unlinked? Will I be able to relink my PSN back to my old EA account through this way? And will I be able to restore my progress?

I would greatly appreciate any help and advices!

Thank you sincerely!
