Description:
Hi, I had Rotten Stache, I wanted to trade it for Timebreaker, when I was in trade with http://steamcommunity.com/profiles/76561198092978187 he added also 4commons and Timebreaker, he wanted me to put Elemental Ice Infusion too with Rotten Stache, and while we marked the button, and clicked Make Trade http://steamcommunity.com/profiles/76561198092978187 that guy just removed Timebreaker, I don´t know how, it must be hack or something, he stole my ice tiny elemental cold infusion too but I don´t care about that, I just want my Rotten Stache back please help me I can give that 4 commons too

I don´t have any screenshots because that guy just instantly removed and blocked me on steam after using that hack or I don´t know what in trading (sorry for bad english but I hope you can understand me )

Without screenshots showing a clear agreement we are unable to process this report, we're sorry.
