Cannot recover my Hotmail Account/Account Recovery not working

I have an email account that I cannot access.  When logging in, I get a message that someone else may be trying to use my account.  I have tried resetting the password, the account recovery, and having a code sent to my home phone number.  Nothing works.  When I get the code sent to my home phone number and enter it, I then get the message again that someone else may be using the account.  I have reset my password twice, still getting the message that someone else may be using the account.  I have filled out the account recovery form twice, both times stating that I have not included enough information and that the account is blocked.  How do I get out of this loop, gain access to my account, or get my account un-blocked?  Thanks in advance!
