How to report with a ticket?

If you have had a negative experience with a player, there are two methods of reporting users: For in-game abuse, including both post- and pre-game chat, please use the post-game reporting tool. For out-of-game abuse (IE: direct messages), **please submit a report to Player Support** Doing these will submit a report to Riot for further investigation. - that what I got from Riot on boards. Q: How to report player if when u r trying to report with Support. Ticket automatically change and says u need to use a board?
