HACKED MSN EMAIL ACCOUNT…HELP!!!!!!!!!!!!!!!!

I had an MSN email account for years that was hacked into a year ago. I have filled out the online forms 50 times, but they can't verify it was my account because the hackers not only changed the password, but also the security question and contact phone number. I have proof it was my account, and I need it back for some emails I had on there for an upcoming court case. I have provided contacts, emails and everything else they should need to verify it was my account. Also, if you go to Spokeo email look up, and put in my hacked email address, it shows ME as the owner. Microsoft has been no help to me thus far. THIS HAS BEEN THE MOST FRUSTRATING THING I HAVE EVER GONE THROUGH.
