Bottom line, after a great deal of sleuthing, I've discovered that an item was sold to a buyer, paid for, and shipped, after the very same item was already sold, paid for, and shipped to another buyer. Ebay "resolved" the issue based on the second buyer's message that they "did not receive their item" as denied and no appeal possible. My mistake that I sent the wrong item. Buyer's "mistake" that they used the "did not receive item" instead of clarifying that they received the wrong item. (Likely due to the few "select" choices). Somehow, the same Ebay item remained listed even after it sold. Help! How can I resolve this? I want to refund my second buyer and do not want them to be charged for return shipping. Is there a way to work with Customer Service after a closed Appeal?
