Yeah,
Email them and ask them to check their HTTPD Conf file.
It's most likely they haven't allowed people to view them.
Also check the permissions on the folders, make your public_html directory set to: 777
in a Unix command just type: chmod foldername 777
Or on a FTP just right hand click it and click "CHMOD" then tick all the boxes.
