player ban

i was just playing comp and there was this jett who was being rude non stop. it started when he rotaded without coms and i didnt see it bc i got pushed by 3 ppl. i tried telling him he needs to give coms, maybe atleast a ping, but no succes. he kept being rude the whole game and ive reported him multiple times but nothing got done against him, not even a chatban. and when my duo said one thing against him got a chatban within the minute.
