Hi, I'm John!
I understand how frustrating this is.
An account cannot be deleted without proper access. What likely happened is your account was compromised. The attacker may have changed the email, password, and enabled two-factor authentication, which locked you out.
In this situation, the account isn’t actually “deleted.” It has most likely been taken over, and since the security details were changed, it may no longer be recoverable. Because of that, deleting the account is no longer applicable.
Should you need further information please let me know.
