My Hotmail.com account has been hacked and I cannot remember my security questions to get in to the account and set up a new password.

How do I get my Hotmail.com account deleted as I now have a Hotmail.co.uk account to take its place? If I can get into it to reset my password that would be even better but as I cannot remember my security questions I am not sure if this is possible.

Many Thanks

Sarah
