Problem whit domain

Problem whit domain

Hi all I have a problem with the domain. I have created the account with this email ZOHO: residencialclausell@gmail.com and I added the domain residenciaalclausell.es 

Follow the steps, check the domain with the HTML method perfectly and no problem, enter the options panel in my account and perfect until suddenly just stood and sent me to the main page of ZOHO. Then, try to access my account again but I was saying that my mail did not exist in the database, went back to check in with the same email and password and let me (It seems that I clear before). 

But here comes the problem, adding the domain again, I said that already in use or is there and I'm in a loop. How I can get my domain? 
because I delete my account? if I was unable to register with it is that no longer existed in your database, I can do? 

Thank you very much for the reply
