My xbox account being hacked

Please explain your question more clearly so that we may be able to help you a bit more. From what I can see you say you are being hacked but if you phoned xbox support they wouldnt just not answer you. I suggest you ring them again so that they can close
yoru account down and investgate it.

What you can do is when the message "last signed on..." pops up, hit your guide button, there are some things there to help keep them from logging in, also if you can get to the settings area of the dash in time, click account then click account security.
there are options to change your password, need a pass code or password at sign in and even changeing your email address.

hope this helps!

If your account has been compromised you will have to call support again and have them investigate. Phone support are the only ones who can start an unauthorized access investigation.

If you want to report the users you think are doing this, you will need to file a complain via the console. Calling out other gamers is not allowed on the forums.

Greetings, MLG TaG Tactics. I wanted to jump in here and confirm what FoomBerry said. If you experience harassment of any kind please take a look at this sticky and follow the steps to report the user via your console:

forums.xbox.com/.../19139.aspx.

If you suspect your account was compromised in any way please follow the steps on this page to secure your account (http://xbox.com/security) and get in touch with phone support as soon as possible. They
will be able to help you with this issue.

Let us know if you have any further questions!
