trust me after a year of messaging this site owner its impossible to reach a deal with him and this is not some regular service mail.com but on thor network . The reason for i dont want to share the email provider publicly is i dont want anyone messaging spamming them and ruining the only chance i have left to get the password and its letting me try unlimited attempts to guess the password without captcha or lock protection but i havent had any luck.
If they keep ignoring it for a year, you should get the message that they are not going to help you, and you should stop communicating with them, check this article and try some of the methods here.

If you exhaust all means to recover your passwords it's time for you to move on and forget this whole thing maybe in the future it will just pop up in your mind when you least expected it.
Move on, and enjoy your life there's more to life than stressing yourself to recover your email password.
