Account Merge Fortnite without email verification?

I have bought an account and I would like to merge this with my main account, but the problem is, if I want to merge the account, a security code will be sent to the email address, but I do not have access to the email address, does anyone have an idea how to deal with the security code?

You write the dealer un unfinished. He has access to the e-mail account

I've already done, at least one email other social media channels, I can't find, only the question remains whether he ever looks more in the mailbox, if the account is connected

Can't you change the email?

No, because if I want to change the email address, a verification code will be sent to the old email address: /
