Thank you for posting this question! To answer it, once a domain is claimed with a specific name, then we do not have the option to change the name of that domain.
Please note that domain names are not changed because they represent unique online identities registered by individuals or organizations.
If you would like to claim a new domain with a new name, feel free to contact us on live chat and we will be happy to assist you through all the steps. Also, you can unset the already claimed domain so it can be free for other users that want to use the same.
