How to report toxic behaviour?

Hi, As you can see is one of my first posts on the forum but I really feel in urge to ask Riot for help. Today I've encountered the most toxic players ever in my entire multiplayer life and I really need to report their toxic behavior (as already did in game) hoping to enforce some just persecution on them. I don't wont to give to the public their summoner names therefore I hope someone of the support will email/pm me since I cant open a ticket (player report ticket no more exists seems). Regards, Oblee
