I can't get into my account

Hello,

I can't get into my old account so I had to create a new one. I couldn't change the old email in my old profile because it no longer exists and it keeps telling me to enter a verification code but I can't get the verification code because the email doesn't exist. I have all the games there and I want to know how I can get into that account without a verification code and how I can change the email in that account.

Thank you
