Hi,

I have tired to sign up for your email hosting with theboyds.net.au but I when I put the mobile number I entered to login in it does not let me and tells me there is an error. 

Can you please release the domain name so that I can start the process again for beginning.

Domain name is: theboyds.net.au

Thanks
