What do i do now?

I forgot my email to one of my pures i wanted to sell, so i requested a change, takes 14 days. I forget and today i check back, 16 days later, and i went to confirm my email. I get the confirmation number and everything, and it tells me it it's like outdated or something, so i click resend. Get the confirmation, and the same thing. It basically tells me the email is no longer registered because i took too long to confirm, but it says 'waiting confirmation' when i log in
What do i do? I tried unsubscribing but it gives me the same error as when i click confirm.
