Another blog published my private email account and doesn't respond to my emails

Hi Support team,
I tried to contact a blog host for the blog http://ouruniversity.wordpress.com/ several times after they published an email I sent them (which I don’t mind) and added my personal email address to it (which I do mind). It’s been a while and every time and again I tried to contact them but received no response. Now I’m quite annoyed and really don’t know what to do anymore. Is there a chance somebody from the support team can help me? The email address I’m referring to is affiliated to this account as well and I can send you guys the direct link via a private message if there is a chance to help me. Thanks.
