My son tried to access his hotmail account, and when he signed in it said that someone may have been on his account.  It said to enter a phone number and it would send a code either by text or by call.  He tried both with a couple different phone numbers and still hasn't received anything.  Called tech support and they said to try and receive it by email, but that option isn't available. Wouldn't even let him sign in to post here. Anyone know what to do?
