Scammed of mats worth 190k

[Weiner]

what happened was, i was trading FK_Aragorn (id: 21115) some mats(2HM,1scale,1steel,4coal,1ravenfeather,2sulpher) for 190k. he put up the 190k, i put up all the mats, i pressed the accept button then went afk for a bit, when i came back i received no gold and all my mats were gone. this was my fault  but he still scammed me.
