Others have said it in this thread, but a Customer Support ticket is the way to go here. Include any screenshots you took. The player will be investigated, logs checked, and appropriate action taken depending on how severe the case and whether or not they have prior warnings.

For what it's worth, I'm really sorry that you ran into such jerky attitude in-game. All online games have rude people. You can't control what people say or think, and the hope is always that the negative ones are the minority and don't reflect the entire community.

In the case of actual harassment, though, it's important to speak up! That's when these support tickets are most important.

Also, thank you for scrubbing these screenshots of other player names and focusing on the topic of community toxicity vs. being angry at a single person. Callouts aren't allowed in the forums partly because we don't want a witch hunt here.
