locked account

Hi all, I had an account that I was using a bit and logging in everyday and I noticed that Microsoft was asking me to update my security and I had 7 days to but I didn't pay attention which is my fault..... now I think my account has been locked down for safety but I've tried to prove that it is me by using another email but once I send then code that it asks me for it then says this '' As you're trying to access sensitive info, we just want to make sure this is you. To continue, check ro*****@hotmail.com for a message from the Microsoft account team and enter the security code here ''

I get no messages at all or emails for another code..... what should I do? please help.
