spam pinging

ok so a few months back,my account got banned because of this.....

so i was playing veigar supp and i think we invaided or some thing because my adc ezreal backed and werent there when the minion wave came so i just took literally like 2 or 3 cs and he started to spam ping the enemy is missing ping so i sad "if u ping one more time ima leave" now the reason i said this was because this happened to me one time.i spam pinged becuase my supp took some cs and he left bot and i was doing terrible because i was 1vs2 and after that i thought mabye dont spamm ping my support so i learned a lesson from it. wich is what i was tryna do to ezreal but riot perm banned my account for that wich is very stupid and makes me mad. so fukin mad. so do you guys think i deserved it ?
