Failed import from svn x2 (can't delete broken project)

Hi There

Two imports from our svn repo have failed halfway through. The result is a 'dead' repository on bitbucket's side that i'm unable to delete. When trying to access them I get "An error has occurred." or 404 if I manually try get to their settings.

How would I go about removing these repositories from out account?
