Who is the super admin for my account?

Hi, I'm looking for the super-admin account name for my zoho email, i must have 4 email addresses signed up with zoho somehow? I tried this account; erikschempp@schempprenovations.ca and info@schempprenovations.ca, and couldn't access the control panel through either. Any help would be appretiated.

Thanks
