My problem is similar but slightly different: My son created a new account from the xbox but got the email address wrong and can't remember the password he picked (he's been suitably lectured on this ;-). We therefore have an Epic Games account that we can't login to because we don't know the password and we can't verify it or request a password reset as the email address is wrong.
I raised a support request with Epic 10 days ago but nothing has happened. Any ideas how long this might take? All I want them to do is change the email address on the account to a valid one so that we can verify it and request a password change. I made the support request from the email account I use for the xbox, so hopefully that's enough proof that I'm not trying to steal the account.
We really want to play Save the World together but I can't link him as a friend from my PC without being able to login to both accounts. Anyone have other suggestions for resolving this?
I am not sure I understand why you can't login with your xbox account. You should be able to access that new xbox account your son created even though you don't have the email/password by using your xbox login, right? PM me your ticket number and I'll ping someone to take a look.
