ive been really silly and sent an item to Russia in good faith that id get paid. Because i was little late sending an invoice i didnt want to risk a negative feedbackso sent it in good faith and said not to worry about the extra postage just pay the uk price. The buyer now hasnt paid despite 2 reminders. If i go to the resolution centre and open a case does that mean i risk neg feedback or does this prevent her fromleaving any feedback ? Im confused . TIA
