Trading bug

On the tRade site it said 47 divine for an ingenuity when I get there dude said he was offered 48 so I said I'd match it, in the tRade it showed the appropriate item, 84% when the tRade completed i received a 35% one AND the person blocked me. I thought this tRade system made it so I had to VONFIRM if there were changes but this did not occur...48 divines down the drain...48.....I reported them but that's not going to make me less poor.
