The moral of the story here is that there is always the chance for some sort of shady interaction. Wether it be with the buyer or the seller. But as I have always advocated, if you have been wronged, do NOT be afraid to call that person out. Like I said earlier, don't be rude, but definitely write a summary of what the situation once. That is one of the only ways that might be able to resolve the issue by bringing it to the public, AND that helps any of our members with future dealings with those people. There is no way to solve this if everyone just keeps their mouth shut.
