None of the 'Contact Us' options work

I am trying to get some help with the software blocking a site which I have specifically allowed (minecraftwiki.net) no my son's computer, but none of the 'Contact Us' options work.  They all give me a popup which asks for my name, email and question and tell me to click continue, but when I do, nothing happens.  I cannot contact via Live Chat, Email, or Phone.  Can someone please tell me how I can get in contact with you people?
