Account lost

I had an account with Star Wars: The Old Republic. The last email I received from them was in April of 2024. I went to log into it again today as a friend wanted to play. I couldn't remember my password, and when I went to reset the password, the email never came to the email I created it with. This has led to me being unable to use my steam account to log into SWTOR, and I can't reset my password either. I'm certain that at some point between the last email being sent, and trying to reset my password, another person must have logged in and changed the email associated with the account. Is there a way to help?

The display name on the account is: StrwbryJam.
