Dear Zoho Support,

Today i trying to register my domain nucleuscapitalsolutions.com to Zoho Mail with email admin subir@nucleuscapitalsolutions.com and phone number +62 818-115-114.
But after enter the verification code get error.

Then i'm create zoho account subir@nucleuscapitalsolutions.com with different number but when trying add domain nucleuscapitalsolutions.com get error message * This Domain is not supported or is already registered with Zoho and sometime get message that this domain already registered with account +62 818-115-114.

Could someone help me ?
