Can someone help urgently?

My girlfriends Hotmail account has been hacked and I have tried so many attempts of trying to recover the account but have had no luck.  I have submitted numerous forms in an attempt to regain access but I keep getting reply's saying that I have not provided enough information, but I have supplied as much information as is humanly possible.  She has some very important E-Mail due through to her in the next few days so it is vitally important to get this rectified.

I hope some one can help
