Fortnite and Epic Account?

I need someone who is really familiar with the Epic account and connection to fortnite.

Since we apparently made a mistake with the connection with the e-mail address (the e-mail address does not exist. And we can no longer change it.

And we've already written twice with epic support, but somehow we always wrote past each other.

And they can't be reached by phone either.

And now? If the support can't or won't help you, then nobody can.
