Releasing a Domain- Account Recovery

I recently created a username and domain address with wordpress. In designing this domain I tried to make simple changes to the domain name and/or username. Although wordpress did not allow me to make any changes. The email address that I had created the account with I was unable to gain access to. So I was unable to verify the account entirely. I proceeded to canceling the account entirely, and tried to create a new account. At that point the username and domain address are now linked to a previous wordpress account that I no longer have access to because the account is now closed. Because I was unable to access my email to verify the account, I never was able to receive any of my receipts, two-step verification codes, urls to verify proof for recovering the account. I was unable to contact wordpress directly, is there any way to recover my previous account? Domain name and username?
Account Domain : https://www.BillsBlogTalk.com
Username: BillsBlogTalk
