14 days ban ??? This is not fair RIOT.

I was in a premade of 3 with my friends and one guy (Who piked up Veigar ADC) started to harass me and flame me. I told him to shut up and stop tilting me. At the end of the game he reported me and I got banned 14 days!!! This is my first offense ever! How come i got banned this long, no warning only because i thrashtalked someone who was doing it to me first. Its the end of the season and i'm one of the ones who invest money in this game for many years already... I'm honor 5 for something Please reconsider checking this case Thanks
