Buyer requested a return and received an immediate refund upon creating the return label. Which seemed odd as usually the item must be returned first. We received the return package today and inside was a tiny empty package of some ear buds. The item they purchased was 26lbs. So we had to pay for a 26lb return label for them to actually keep the heavy item they purchased and were already refunded for and then they just sent back a 1oz empty ear bud package. So we lost our item, we also lost money paying for the return label. We also cannot access "manage returns" for some reason. It is just a blank screen. But we do know the order number. How do we report this and get our money back and keep this from happening to somebody else?
