First of all, excuse me for my english ! I hope you will understand me, and help me to resolve my problem.
Yesterday, I was playing with my account, everything was ok, and suddenly I get a message : "your gamertag is connected on another xbox" (I don't know the message in english, I translate it from French)
So, I tried to recover it during hours, deleting it and redownload it ! Nothing was working ! I tried one more time, and I succed to get it back ! I changed everything, informations, passwords, etc; but something was wrong with my account ! My gamerscore was changed ! So I did some research, and I heard about GS modification, and I know that you can be banned for that ! I haven't done anything with my GScore, no modification, nothing at all, for various reasons ! I don't to be banned for this type of thing, and because i'm on the xbox live since 2006, i knew a lot of people who where banned for that ! So I know what you can get if you're doing stupid things with GScore ! Now, i'm trying to know what I got to do ! I called the support, they told me that they can't do anything for me... I got a credit card on my account too, and no transaction was done; everything seems to work great on my account !
So i'm asking this to you : what can I do ? I'm kinda lost, i'm going to buy my Xbox One in a few days; and I want to use this gamertag (it means a lot to me, it was my first account) I really don't want to be banned because of something I've never did !
Thank you a lot; excuse me again for my english, and have a nice day !
