In game Matchmaking

Why the heck are you gonna give people negative rep for quitting early And not replace them with in game matchmaking…I play at least 3 games a day and it ends up being me against the entire enemy team and I don’t want to quit to lose actual Xbox rep but a better way to fix the issue is to probably send halo back because you continue to screw up multiplayer…get your crap straight 343 and ask the community for what they want and stop thinking about what you want

I got banned from halo 3 last sunday today is sunday im still banned when do I get unbanned help?
