I cannot access my hotmail accounts

I keep getting this message
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 ask you to provide us with a mobile phone number where we can send you a verification code and we'll add this phone number to your Windows Live profile for future use.After you enter the code, you can change your password and sign in.
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.
When I give my cellphone number and wait for a verification code, nothing happens. I have tried with two different hotmail accounts. Have I been hacked or is this another scam. I have tried to run antivirus, but dont really understand how to do it. Any help please !

Format my number! So far they haven't sent me a number. :-)
