Got banned because temmate tole me to "kys"

In champ select my teammate begins the chat with cursing because they got support, don't know which words he used tho because they were starred out but i could tell he was mad, he then hovers kaisa who i ban so we dont get a kaisa support, then he tells me to kys twice. When the game starts i say report cait she told me to kys twice and then cait reports me at the end of the game and i get a 2 week ban lose all my honor and she gets nothing cus i forgot to report her in the end of it
