Stolen, hacked account getting no satisfaction with advise to reset account, as my password has been stolen

My account has been stolen/hacked, my password has been stolen, I have tried trying to access it, but it seems my security questions have been changed.  I need someone to look at my account, I have tried all the avenues to reset my account, but I believe my password has been compromised, and all the security settings changed, this only happened a few days ago.   I have used this account almost entirely on my home computer, therefore if someone looked at my account, they can see, the password was changed on 3/4 sept 2013, and that my IP address is the common address, I can also supply more info on e-mail sent and received, but cannot get someone to look at this.  As a journalist who has had this account for over 10 years it is imperative, that I not only get my contacts back, but that they are protected.
