it looks like someone else might be using your account

I am a long time user of hotmail, i have been using the service as my main email for years. I have now come across the message "it looks like someone else might be using your account". I followed all the instructions to try and recover my account with what information i could but its an old account which doesn't have my most update information. However i tried my best to answer the questions.

I got a response rather quick saying that my first attempt had failed. So i tried again with some more information which i thought would be better and expected to hear back within the 24 hours i was told to wait. It has now been six days, nearly a week since this problem had happened with no reply. Now before anyone from Microsoft or whoever else says have you tried password recovery, the answer is yes and again it has been more than 24 hours since it has been sent. I am using an alternative email to get answers from Microsoft and I have to use my father’s email address to sign in just to post this! 

Any suggestions with be most appreciated!
