Someone has used my email address to link their EA and PSN account

Hi guys, I just purchased a digital copy of Battlefield 6 for the PlayStation 5 and after installation I got a message saying my EA account has been banned when I don’t even one to begin with!! 

ive created a new EA account and it shows I don’t have any suspensions or bans, when I tried linking my EA account to my PSN account it says it’s currently linked to **bleep*******@maillv.com.

i submitted a request to EA to get help on this issue, and got no response after 2/3 days. I managed to get in touch with someone a few days later on their chat system and with all the details I provided they said they can’t give me access as I got some details wrong which makes no sense as I was logged into my PlayStation while giving them all the details they asked for. I bought a game and can’t even play it because some clown has used my email address to link their EA and PSN account, I tried request a refund for battlefield and it says I’m not eligible as I bought a digital copy.

any help/advice will be greatly appreciated.

apologies if this topic has been posted already, I’m new to this and just trying to get online with Battlefield 6.
