Error sign up my domain

Error sign up my domain

Previously I tried to create a corporate email with the domain: www.stratton.ind.br, but when I went to the verification step with text message via mobile phone, I did not receive the message and I noticed that the telephone number was incorrect, therefore I could not verify. I tried to go back to the stage but I did not succeed. Again I tried to register but got the following error message: the domain is already registered with Zoho.

I need them to release the domain so I can register the account correctly.

I thank you.
