Large timed bans increasing everyday for no reason

Over the past few days I have been experiencing an abundance of progressively increasing timed bans from arena multiplayer (current ban is now at eleven hours) for disconnecting from games that are already over, in other words the victory or defeat screen is in play. There are a couple of reasons why I believe the problem is on 343s end. Having just come from speaking to a Microsoft representative he told me that this continual problem that I and many others are experiencing is an in game issue. I also have pretty decent internet and almost never get disconnected from a match, unless it’s extreme weather conditions which I am not expiriencing, but now it is happening on a daily basis and with every disconnect follows another disgustingly long ban. This is extremely unfair as I have paid very good money for this game and absolutely love halo and I have the right to play this game as much as anyone else without the gross interruptions of these bans. I hope this can be resolved shortly so that I can get back to kicking some -Yoink- in slayer and breakout.
