Hotmail... HELP ME!!!

Hello, I joined just so I could ask for help here since apparently hotmail can't help you unless you're able to actually LOG IN...

Yesterday I tried logging in. I'm positive I had the password right all three times I tried it, and then they blocked my account and I can't do anything to log in.

The email address that they tell me they'll send my new password to is my mother's old email address that she doesn't use any more and that has long ago been closed down. I have gone through all the frickin' help pages on the hotmail website (at least the ones you can see when you're NOT logged in) and I can't find a solution to this.

Is there anything I can do? Was my email hacked? HELP ME!!!!
