There's another thing you can try. WHOIS the domain name, see what the information is on who owns it, and look for the contact information on the domain name. It might be a different address and phone number. Just go to www.whois.sc, click on the "Domain Explorer" tab, type in the domain name (without the "www."), and hit "Search" or your Enter (or whatever it is if you have a Mac) button. That should bring up the domain information.
