Cannot sign in due to an old email

Hello, everyone!
I want to restore my old account, but when I use my password I get the warning “Your password is in a list of passwords commonly used on other websites. You must update your password to continue using GitHub.com.”. As a result, I need to use my old email to reset a password, which I do not remember.
I created a ticket in Github, but I am not receiving an answer for almost 10 days.
Is there a way to restore my account?

I’m afraid we’re unable to handle queries about account access in the community forums. You will have to wait until your ticket is reviewed.

Please note, do not open repeated tickets - that will delay a response, not expedite it.
