I had a similar issue recently with eBay.
I just purchased an item nearly a month ago now and during check out the wrong address defaulted, an address I havent used in years on eBay and is a mystery in itself how it was defaulted as the confirmed shipping address considering I've had things shipped to a different address over the years. Anyways, I catch the mistake immediately after the order has been processed and I enform the seller within 10 minutes of the mistake. Long story short, it was delivered to the wrong address and sent back to the seller, the seller said the item was returned due to it being the wrong address in an email conversation with me, and eBay will not refund my money and the seller will not ship it to my current confirmed address unless I pay for shipping again. Suggestions? Legally can eBay decline my refund for an item I never received and the seller said they have back in their possession?
