Falsly banned on Halo: Reach (MCC) for 7 days.

So, I’m kinda confused. First of all, I would never cheat in a game especially not the game I grew up playing and played it ever since then but today I got banned for a week and it will be revoked the 12/24-2019. I kinda just wanna get things straight because I haven’t cheated or anything but I have gotten a little bit mad in the Local Chat and said some words every now and then because of people blocking me when I jump somewhere (on purpose) or just like making me mad via typing stuff that gets me on the hook. So ofcourse I reply (angerly) and I don’t know if you can get banned for that or not but I assume that’s the reason otherwise it’s a big false ban and I would like an appeal because I “LOVE” that game and I’m really grinding hard for that Tier 100 right now aswell so it kinda made me mad and sad. But the behavior is something I can deal with but it’s just kind of annoying which triggers my short fuse.
So please help anyone, I would mostly just like some information about the Ban system since the Ban Note didn’t have any sort of information at all except from when the ban is Lifted.

Please use the ban thread pinned at the top of the relevant MCC forum for any queries on matchmaking bans
