Negative feedback can be withdrawn or edited by the buyer/seller, all you need to do is contact the buyer/seller and ask them to withdraw the feedback or change it to positive by clicking on the "Edit" button. PlayerAuctions won't remove any feedback without confirmation from the member who left it, or if it's a clear abuse from the buyer/seller.
If you believe that a buyer/seller has unfairly left you negative feedback, you can appeal the feedback to us.
