why i am banned for unsportsmanlike conduct

Does anybody know why would i get banned for it? last game 3 days ago, dont remember being toxic, last week i got a warning for spamming since then i think i wasnt even using chat. Is there a way to contact faceit support in a live chat or something i wanna know what i did wrong. https://www.faceit.com/pl/players/---exec--- (if moderator is somehow reading it this is ticket number (6743071))
