Accessing hotmail address which may have been hacked

My hotmail account was hacked into some while ago. The account was recovered and I changed the password and security settings. I set another hotmail account to use as my main account and have used this rather than the old account. However, I have recently tried to access the old hotmail account. I had forgotten the old password and when I went through the various recovery procedures find that my security question has been changed and the contact email address has as well. I have tried the recovery procedure but that has not worked as it is sometime since I used the account and I cannot give enough of the details required about email traffic to satisfy them. Is there anything I can do. I am concerned someone is still accessing the account and I would like to close it. I have not tried to access this account since the change to Outlook
