Unlink steam account

Hello Support Team,
I am writing to request an urgent unlinking of my Steam account from my Path of Exile account.
Unfortunately, my Steam account has been compromised (hacked), and I no longer have access to it. To protect my Path of Exile progress and prevent any unauthorized access or potential damage to my items and characters, I need to disconnect it from the compromised Steam ID immediately.

Here are my account details for verification:
Path of Exile Account Name: zansake#4471
[Removed by Support]
Character Name(s): in Mirage Leage : Boison_ ; Big_Boyz ;SuckwaveTuTem
I would like to switch back to using a standalone email and password to log in. Please let me know if there are any further verification steps or information required to process this request.
I've been trying to email support@grindinggeargames.com, but my messages are constantly being delayed.
Hacker logged into my account. Although they haven't done anything malicious yet, I am very concerned that they might compromise my account or take further unauthorized actions.
Thank you for your quick assistance.
Best regards,

I’ve sent an email to support@grindinggear.com
