Was ranked a 23 in halo 3 team slayer. Had close to 7000 kills and 6400 deaths in multi player. Turn my Xbox on 2 hours later and my rank is a 13 and half my kills and deaths are missing. It's as if 2-3 weeks of gameplay has been deleted.. even now online is says I'm ranked 14 in h3 and on my x box I'm a 13. This makes absolutely no sense . How are beta errors still happening and what can be done to fix it. Even my gameplay footage of the ranked games are still on my profile. Who do I get in touch with ???
