Help if you can any advice? Hacked account cant recover would really like it back!

Okay so this is actually my cousins problem though i have too use my account too share this with you and hopefully someone will know the answer!

Well first off my cousin would never give out his information too anyone he's not that dumb.

So i was just playing on xbox live and I get a text from him saying hes been hacked you know he was freaking out ( on my phone not xbox related) he said he was playing call of duty modern warfare 3 when a guy in his game lobby invited him too the party and
he thought nothing of it so he joined and he said they were talking casually 5-10 minutes in he gets disconnected from xbox live and when he tries too sign in it says he needed too input his password and he did and it didnt work now this is when he messaged
me and when I heard the story I remember the time one of my friends had said that it is possible too get people ip addresses and things like that just from being in people parties and I find that completely stupid! but however its the only logical explaination
now his father is the one that made the account so I talked too him about it and he is really worried that all of his other emails and passwords will be taken so I tried helping him out by trying too recover the account and sadly enough the phone number on
the account is no longer active and the email was from yahoo and was deactived due too being inactive for 12 months so really there is no way for him too get his account back unless any of you helpful people could find a way I have tried the solution where
if you have enough information theyll send you an email but its been 24 hours and I havent recieved one yet so i really dont know what too do I really feel for this because he has worked hard to on his profile and I would hate too see him have too restart
all his progress + the chance of these "Hackers" getting the rest of his families passwords and such

Please reply if you know anything that could help! Thanks!

Lost friends list!

Hello everyone, I was hacked back in December along with many other people. As some of you may not know, when the account is finally returned, the friends list may have been deleted. It doesn't happen to all hacked accounts, but it did occur in my case.
I would really like to have a lot of those people back on my friends list instead of having them frequently adding the person who has my old GT. (Waur) Is there any way to see past friends lists, or recover lost data such as saved games and videos? Any help
would be great, thanks!

 

Profile question

This would recover the Gamertag back to your xbox.

Sometimes if there is an account that is hacked if you recover before instructed it could flag the account.They were probably just letting you know it was ok to recover.
