I´m Sorry my English is not Perfect (Im from Germany) I Translated with Bing translator.
I signed up a few days logged in and suddenly my Gamerscore on 8900 was although he was before 1600. Then I phoned at Microsoft and they told me how it can be reversed perhaps.You told me to my profile I did so then delete (which I did before sometimes and it accidentally got deleted my scores) but it didn't help. Then I called again and he says I time that delete cache you want to delete the profile and press then 2 x LB RB X then download again the profile that helped anything.I'm constantly scared that someone thinks I hack and I'll get banned: o.I did me once on the Internet smart and after a long search similar cases which found said that Microsoft can delete the game score. I see this as the only solution because you can pull off yes no 7300 G me I think or? I would ask them to reset my Gamerscore.I play since no single-player anymore because if the Gamerscore is zeroed I must start again therefore, I wait until it is reset.
