Request To Unlink SWTOR Account from Steam

Hello,

I would like to request the removal of the old SWTOR account that is currently linked to my Steam account. I no longer have access to that old SWTOR account and I would like to create a new one, but I am unable to do so because my Steam account is still linked to the previous SWTOR account.

Unfortunately, I no longer remember the email or username used with that old SWTOR account.

Could you please help me unlink my Steam account from the old SWTOR account so that I can start fresh with a new one?

Thank you in advance for your assistance.

I have attached screenshots of my Steam profile and SWTOR game page to help verify that I previously played the game through this Steam account.
