Perhaps it’s a good idea to leave him negative feedback on his profile? You can explain there what happened and the moderators won’t hide that. Leaving negative feedback (if necessary) helps people know how trustworthy a trader or seller is.
Yeah, well then he’ll leave you revenge feedback (negative) for no reason.
Please be specific, as your accusations are not correct in my opinion. Throwing out random, unsupported accusations is insulting. Without specifics, you’re just throwing rocks.
Keep in mind that we are not directly involved in trades and any disputes are your word against the other guy. I myself and other mods have been involved in trying to mediate some disputes, including revenge feedback, but there is little we can do other than talk via PM to the individuals involved to try to come to some agreement.
