There's a few players who express racist ideology been reporting them but nothing happened what to do
I can only suggest contecting Live Support on this issue.
They will take your complaint and your contact information, review the player interactions and decide on what steps or actions are best suited.
After a perscribed period of time, Live Support will contact you with information on what measures or actions they have decided to take.
In the meantime, you always have the option to block someone that you do not wish to interact with.
