I'm sorry but we can't mediate this deal for you. We have no way of knowing what actually transpired with the deal. We don't know what was promised, what was delivered or if either party is telling us the whole truth.
I agree that nothing is worse than doing your part and then having someone else not only fail to live up to their end, but also try and blame you for it not working out. I wish we had a better way to deal with retaliatory feedback. Ebay's answer is to allow both parties to mutually withdraw, but that doesn't actually warn users against bad traders/sellers. We're always looking for good ideas on how to improve the system so if you have any, please share.
Pretty much the only time we will mediate Feedback or a B/S/T deal at all is if one of our mods
was used as a third party
. Then we at least know what happened.
Before you do another deal on PbNation, we strongly recommend you read the B/S/T Tips
. They might not have saved you this time, but there is a lot of valuable information in there.
