where are my halo statistics ?

I played many halo games including halo reach and all my statistics are not on waypoint. why? I am mad! fix this! I want all my statistics back ! for both of my accounts !

What do you mean by “both of my accounts”? If you change your gamertag, your stats are out of sync:

> If you’re here because Waypoint is telling you that you haven’t played a particular game, then your service records will be out of sync. This usually happens if you have changed your gamertag since you last played one of the older games (Halo3, ODST, Reach) and is relatively simple to fix.You’ll need to boot the games up again and play something. This can either be campaign, multiplayer, forge, etc, - playing the backwards compatible version of a game should also work.Halo 2 is the only game that cannot be fixed using this method as the servers are no longer active to sync with.
