I didn't want you to completely remove the domain, just remove the redirection, but that's ok. Just go back to "Parked Domains" at your cpanel and add xploitedmedia.co.uk as a parked domain again BUT don't add any redirection. Just click Add and that's it. After about 24 hours you should be able to see your domain without it being redirected.
Also look inside your root .htaccess file and tell me if you see something like this:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^xploitedmedia.co.uk$ [OR]
RewriteCond %{HTTP_HOST} ^www.xploitedmedia.co.uk$
RewriteRule ^/?$ "http\:\/\/xploitedmedia\.heliohost\.org" [R=301,L]
