PS5 account mystery

Hi everybody! I’ve been playing for a while, really enjoyed this league and reached endgame for real this time so I’ve had a bit of time to enjoy async trading. Now I wanted to try selling a bit of stuff but realized a big problem…

My PS5 in-game name and number “xxxx #1234”

Is not the same as the one I have linked with my email and everything on the poe2 website.

So that would explain how loot filter doesn’t seem to be working but…

Now how in the hell am i supposed to either link this account to the one on the website or even know which email it is linked to? I don’t have any info on the ps5, looked everywhere online.. I’m freaking out a little because I’ve already spent a bit of money on microtransaction on this one account t so anyway, would love some help :)

Thanks a lot!

TLDR : PS5 is linked to mysterious account, how to recover info or link to website account?
