This domain is already associated with this account

I am trying to create a new bussiness email with domain: www.hyelinkglobal.com
I cant finish the register due to the message  This domain is already associated with this account " o*****s@h*****".
I dont remember creating this domain in zoho before. I dont know if it was me who created this, but whoever created, I cant redefine my password because the admin account is hyelinkglobal.com   and i cant access the mail panel.
How do i create a new account with the domain name?
