Delete CRM Account

Delete CRM Account

Hello,

I want to delete a Zoho CRM account I created with ID ( info@bullbeardevice.com) and want to use this same ID as a user to my another ID. But it says that the account is a part of the organization and I am supposed to contact the administrator of that organization. But I never created the administrator Id they have mentioned  ( administrator@bullbeardevice.com )

Any suggestions on how to delete this account?
