getting banned

so i got banned once from matchmaking for quiting twice in a roll which is very understandable but now everytime i finish a match without quiting i get banned again, and again, and again this is the third time it has happened and now it gave me a 9 hour ban…i got it the first time and ban was well deserved but 4 times in a row is a little excessive and its really starting to annoy me.

There is a ban thread stuck to the top of the Halo 5 section.
You’ve quit 9 out of your last 20 including four in a row.
