I am currently under verification and eBay said I need to wait for all my sold items to be delivered so that they can proceed the process. However, the order was untracked and eBay said they can confirm the item as delivered through the chat between me and the buyer. So I approach the buyer and ask whether the item was delivered (I know most people ask not to do it), but the buyer didn't reponse to my message. Is there anything I can do right now, like just offer a refund as it is just a 4 pounds thing.
