I've recently set up a website with a smaller hosting company. The plan has a dedicated IP. They sent me emails to say it's all set up, but now their support channels are all unresponsive even though they say it's open 24 hours.

In the File Manager in the cpanel I've put an index.html file in the public_html directory. But when I point my browser to the IP address given to me, it comes up with the cgi-sys/defaultwebpage.cgi page.

What is the problem?

I haven't set the name-servers for my domain yet, but that shouldn't be a problem because I am using the IP address in the browser.

Note: I don't think I have access to ssh.
