Your account has been blocked....

Hello,

i am having nightmares as my hotmail account is being blocked but i believe its more to be hacked :-( here is the messages i got... i really need help, please .

Your account has been blocked
Why are you seeing this?
Someone may have used your account to send out a lot of junk messages (or something else that violates the Windows Live Terms of Service).
We're here to help you get your account back.
What do you need to do?
We'll walk you through a few steps to verify that you own the account, then have you change your password in case someone else has been accessing your account. It should only take a few minutes and then you'll be unblocked and on your way.
We've cleaned your account settings
Often customers get here because someone else has access to your account and are using it without your knowledge to send spam. To protect you and your contacts, we've removed any Hotmail auto-replies or linked accounts you may have had.
( then i moved on to the next page : )
Where should we send your verification code?
Here's the contact information we have for you.

{here's the problem i have - the other email address is not mine!}
and i cannot change to another alternative email address.

how do i solve this? appreciate if anyone can assist me with this.
Cheers
angel
