My website has been deleted?

HELP! I use outside hosting with Go Daddy and everything on that end is okay but when I open up my website (undertoneonline.com) it looks nothing like it should and when I click on a link to a post or page it diverts to a page that says “undertoneonline.wordpress.com is no longer available. The authors have deleted this site”

What does this mean and how can I get my site back?!
