Changing emails

I have emailed support about this, but I understand it could be a while before someone can get to it.

I want to change the email attached to my account. The old email address has been deactivated. The current process for changing emails requires using a link sent to the old email address, which I can not access.

This is all an extension of an issue getting early access going. I have used my code in steam and it just gave me the game, but not early access. Both steam and my poe account say I do not have early access. I have my account linked. I was hoping I just missed a step and I got a separate code sent to my email for the early access. Just hoping to get this all resolved soon, thanks
