This is Domain Name Group Australia. They are domain name scamsters who send out "invitations" to register new domain names that are very similar to one you may own. However the documents look like an invoice to renew your domain. Its only when you read the very small print do realise its not a legitimate invoice. Avoid. Do not use. Do not call.
