olivia you need to open a ticket with bravenet above where it says if need assistance open a ticket in the support center
since you made the site and decided to neglect it and didn't keep up with your site and more you now have learned what can happen if you don't keep up
if you were going to just waste it you should have deleted it LONG ago or not even made it
so now as said open a ticket in the support center and since you have yahoo as your e-mail address now you will have to write down the ticket number and wait for bravenet to answer you by watching your ticket online
then when bravenet answers you login and delete your files from your site and your website and then delete your accouont
