All actions denied on MS SQL Server on Go Daddy Hosting

i have a website hosted on GoDaddy and I need to create a database for it. So headed to the Databases section and created a MS SQL Database then on my local pc I tried to access the database via SQL Server Management studio, I was able to login to the database but I cannot make any operations. I get it does not exist or you do not have permission. So deciced to go the Security tab, then Login and tried to change my username that I'm using to systemadmin role but I also got Cannot alter the server role 'sysadmin', because it does not exist or you do not have permission. What could be the problem? There are no other accounts on it. The default sa account is disbaled and I can't enable it coz it will prompt no permissions etc.

I don't understand it. Why GoDaddy allows me to create a database but with no permissions or rather I cannot alter it. Anyone facing the same issue? Thanks
