I sold a sweatshirt on eBay and realized I made a mistake and that sweatshirt was no longer available. I notified buyer and apologized many times. I don't feel good about it but I can't do anything - that item was oversold. Buyer is very angry as he was getting more than a good deal on this item. I filed a Mutual Withdrawal Agreement to get my fees back, but buyer responded that he still wants to complete the transaction and I didn't get my FVF back. So, what am I supposed to do now? I don't have the sweatshirt, I already gave him a refund, what can I do so that eBay refunds my fees? I already paid for my mistake in listing fees, what are my obligations to the buyer? Please advise.
