Change domain key from dropbuyexpress.com to dropbuyexpress.com.au

Creating the support ticket as per comment reply to update my domain key.

Hello !

I have lost my domain and changed it to new one. How I can update my domain and delete old one, although website is unavailable.

Please note that, my support has expired, although I did not ask for support, as I can handle myself. I can not see to create any support ticket.

Thanks
