After 15 minutes of searching your database, still haven’t found it except for instructions to "Contact Us’ and this is the only contact form i could find. How do I cancel my ENTIRE epic games account?
Please fill out THIS FORM to contact Epic Account Support. Make sure to enter as much detail as possible to help them assist you further. They will reply to you by email.
It says Fortnite, but it’s currently being used for UE4 support too, just select a random game mode since it isn’t needed for UE4.
