Can't create account - says account already created

Can't create account - says account already created

I am trying to set up a new users for myself in Zoho and when I try to do so it say account already exists. But it doesn't.  I created the original account with for example info@mydomain.com but entered my actual name under first and last name. Now I'm trying to make an account for my first name but it won't let me. I went back in to the info@ account and changed the name associated with it thinking this would work but it was a no go.

How do I fix it? 

I can't even delete info@mydomain.com now.

Frustrating experience so far.
