A 56 Hunter named Vysr, from the guild <Horizon> accepted full materials (22 devilsaur leather, 60 Rugged leather, and 2 rune thread) for Devilsaur Gauntlets and Leggings under the pretense of crafting said items for a fee. He immediately left the group after accepting, and went offline without replying to any of my messages 2 minutes later. I had whispered him after a repeated spam in trade, in which he offered to craft Devilsaur gear for a fee. He has not come back online since, neither has anyone in his guild. Is there anything i can do against this? I have no screenshot of the trade (i wasn't assuming i would be scammed after what seemed like a normal conversation), and our chat was quickly spammed out of reach by the World and Trade channel.
