*.wordpress.com Subdomains

Hello,

I currently support a self hosted wordpress.org site for [ redundant link removed ]. There is a default mock-up page reachable at wordpress.com which I did not create and I would like to have taken down however I cannot find anywhere to disable this page.

If someone can please help me understand where this *.wordpress.com sub domain is managed, it is much appreciated!
