xbox says im not banned but.......

just wondering why my account and console show a temp ban from earing credits on reach but xbox is showing I have no such ban at all

That ban is specific only to reach. not any other games.

so how do I find out why the ban was put on and when it is goin to be lifted?

You were cr banned for getting 0 kills in a game(s)

24-48 hours and will be extended with repeat offenses. Ban will not be overturned. Your only option is to sit through it till the clock runs out and not catching another 0 kill game.

Here is one point in your game history where your guest earned 0-kills
