Unable to setup domain for Mail Hosting

While adding my domain www.takeourtrip.com it show * This domain is already associated with this account "*****28".
I think my website designer have created the account with 9776817528, but right now he is not in touch. Please suggest how could i get my admin details. If possible please delete my account 9776817528 so that i can create a new one. The domain and server control panel details is with me, in MX records there is no mention of zoho.
