You have to call Microsoft, you'd have to give them all the info from when you created the account. The account will be banned off online for 2 weeks, while they investigate it and get it back. If they get it back, they will either email you it or call you back. They also restore all Gold time that was used, also you get 800 MSP to change your name that way the person who ever hacked it doesn't know the name to get in contact with you anymore. Also they give you an email self-registered by them on the account already. That way the hacker cannot recover it as they do not know what the information is. I've gone threw this a few times with this account.
