i can’t unlock my apple id account.

hi, after several attempts of remembering my password my Apple ID account has been blocked. But then i remembered my password, and when I entered it, there was a message that I need to unlock my account. There are two ways of unlocking: email and questions. I don’t remember the answers of the questions because i created this account some years ago, and about email adress: this email is blocked so i couldn’t get message about unlocking. I really don’t know what i have to do. I’m trying to solve this problem but there is no result. I hope you will help me. Thank you
