Epic Games Account Hacked and Email Changed Without My Permission

I have access to my Epic Games account, but it has been hacked. My original email ending in @gmail.com was replaced with one ending in @rambler.ru. I checked my Gmail account, and there were no suspicious login attempts. Clearly, my Epic Games account has been compromised.

I have proof of ownership, as I have receipts for purchased games in my Gmail account. However, when I contacted Epic Games support, they responded saying that I am not the account owner. This is extremely frustrating and unfair.

I urgently request that Epic Games review this case thoroughly and return my account to me. I am willing to provide any additional verification if needed. Please resolve this immediately!
