Well by all means you can contact support to see if those are correct. All im saying is from what i have seen reports are seen through by someone. They also give you chatlogs, granted that might not do justice because they really only give you the recent chatlog, again though im sure if you ask them through a support ticket they'll give you more evidence. its just really hard to tell if someone is actually telling the truth on the internet. Anyone can come up here and state they said, or did nothing wrong, and yet when we see chat logs either from the player, or from a rioter (with the permission from said player) it usually comes to the conclusion that the reports were legit.
Dont get me wrong, your post here have been very calm about the matter especially when normally people who get ban do nothing but be toxic on the forums because they feel their reports/bans were unjust. so from that alone it only says so much. i would suggest to contact support. there are people who are wrongfully reported/ban, and again if you feel that way by all means contact them!
