If you want to log into your account but your email cannot work and you cannot receive a verification code, we can look up the verification code for you. You can send the code to this email address again and let me know it was sent. We will provide code to you.
Since account number and email address are one-to-one relationship, we can not change a account's email when the email doesn't work. The solution of it is to download all the files locally from the old account and open a new account with a new email.
