Problem with my achievements

If this is the same gamertag that you were using 3-4 months ago then perhaps the score was reset. You should post in the suspensions forums in this case.

forums.xbox.com/.../41.aspx

If your account was offline during that time and you recently joined Live then achievements won't carry over from then.

Sorry but part of the punishment when your caught modding your gamerscore is having "cheater" on your profile for the life of that profile,it will never be removed.

More info about gamerscore resets can be found here

Well thanks for nothing, I did all the steps and didn’t work.

1. In the time I waited for a response, and the time I waisted following those useless steps, I could have beaten (again) the half of the game the achievements don’t recognize.

2. Next time instead of sending the users into a useless path of “solutions” fix the games and its achievments recognition system.

The steps are meant to help, and the survey at the end isn't meant to immediately unlock the achievement for you. It's designed to allow our teams to know of issues. We appreciate you bringing this to our attention. Thank you, this thread will be locked.

Just Sign xbox.com and I have 46,304G. The last 2 achievements were unlocked on FIFA 15 (1)and Destiny (1). The achievement of PvZ does not appear in the game or in my recent achievements unlocked .. do not understand.

Well, I was taken back to zero and I gathered again on the new games, I just want to remove the word cheat
