Gamerscore on xbox 360 got reset

I got forza horizon 4 on pc today and saw that all my achievements on the 360 no longer counted towards the total

:)

 

Someone is modding me for free gamerscore

Some guy is modding me some free achievements and gamerscore on me and I got banned. It reset my gamerscore on xbox 360 and I looked on xbox one and there 1000 gamerscore was still there. Do you know how I remove that achievements
to 0 gamerscore? I need to fix it and I need to remove that achievements. Please help me.

 

A question for a friend

So basically I "modded" for 5 gamerscore because you get nothing for the second one. Who would waste their time modding for gamerscore, 5Gamerscore. And l got reset on Xbox one games room not just 360 an example of a game that was reset on Xbox one is Minecraft.
Says the date and when i unlocked them yet i got nothing. How come Xbox support says you can't see who unlocked achievements offline as an ambassador yet you can?

 

Hi,

So maybe here is why your G score was reset: Gamerscore corrections

 

check that you log in with the same account as you do on xbox 360

 

So was it a gamerscore correction?

 

That's when somebody or yourself modded the achievements of a game to unlock them all but if you modded it your achievements on 360 will be reset to 0 for that game and you can't unlock them again
