I have an old Hotmail account which I have used extensively for gaming purposes and unfortunately after deciding to play on a Retro version of a particular game, they have used my registration information to successfully hack into my Hotmail account. They have changed my Hotmail account password and I can no longer gain access to it.

Whenever I try to retrieve my Hotmail account through 'Forget my password' and request to fill out the questionnaire for a validation of proof, the email of my account then changes to another email and shows that I am no longer trying to retrieve my original account but an unknown account that has been linked to my account. I am unsure as to how I can retrieve my account as the security question is set by the hacker as well as the back up email.

Help is widely appreciated, I really want to be in possession of my account again. Thank you :)
