Account Recovery - Linked Steam account compromised

My Steam account was recently hacked and then recovered. However, the person who stole it changed the email address of my linked EA account. I no longer have access to the EA account associated with my Steam profile and I cannot play Battlefield 1. I have my Steam purchase receipts and original account details ready to prove ownership. Please help me update my EA account email to my original one.
