Unfairly started with 2 week ban

I just got a 2 week ban, i admit i was toxic and i deserve punishment but i didnt get a warning, not 10 day chat restriction, directly 2 week ban, i have never gotten banned im pretty sure, i rarely get tilted in chat and get honours almost every game im sure im not reported often. its just wierd for me to be punished so heavily... 2 weeks is alot i think i deserve a chat restriction or 3 day ban but 2 weeks?
