Como puedeo recuperar mi cuenta icluod si se bloqueo por intentos fallidos

My iPhone was stolen, I try to enter https://icloud.com/find, and wrongly enter the password of the account, consequently I got locked out.

I try to recover the account gives me two options:

send an email to the account that ends i*****.com (which I don't remember and I don't have access

the confirmation questions, but it does not recognize the answers

How can I do in this case
