No admin password, can't delete anything

No admin password, can't delete anything

Hi,
 
I recently signed up to zoho using my existing google account.  I was testing the mail functions with my own domain and created a couple of users etc.  But then when I went to delete them I couldn't because it kept asking for the Admin password which does not seem to be my password which I use for my google account.  I do not recall ever setting any other password anywhere and I can't even "reset" the password because I need the admin password in order to reset the password (seriously!).  Looking in the Help and forums tells me nothing also.
 
This seems to be a fairly major bug.  Did you not think about this when you added logging in using other credentials?
