Xbox Live Membership????

Question

My Xbox Live Membership expires this week and I was wondering how I add my months onto my pre-existing membership. Can I change my gamertag also without paying microsoft points when I add the months?

Answer 1

WELL IF U WANT YOUR GAMERSCORE AND YOUR LVLS AND THAT   U  WILL HAVE TO PAY FOR A GAMERTAG CHANGE

IF  U JUST WANNA PUT MONTHS ON IT THEN JUST GO ACCONT MANAGEMENT MEMBERSHIP AND ENTER CODE AND IT ADD SOME MONTHS

Answer 2

You can get it change by having 10 friends file a report of you having an offensive GT then you'll be forced to change it.

And to add months, you can buy them directly from the dashboard or you can go out and buy a prepaid card.
