Need help with updating my account email

Hi!

My school email address expired and I no longer have access to my original school email address associated with my Figma account. As a result, I currently cannot access any of my files under my Figma account. Please help me update my account email. 

I submitted a help request a week ago with ticket number #1676497. The AI support agent haven’t get back to me since. I have a project deadline coming up, so please someone help me update my account email. Thank you so much!
