waypoint problem!!!!

hey there, can anybody help me with my halo waypoint problem on my xbox 360?
its saying i only have 50 gamerscore across all halo games when i have somewhere in the region of 4000. this is really annoying as i cant recieve any of my rewards or anything and is basically making my waypoint useless to me. i would like to get this sorted before halo 4 if possible

It is a known issue and will be fixed when it is fixed.

The good thing is that your achievements are saved to your account and your Xbox so that when the bug gets fixed your real score will come back fully.
