The seller provided a fake tracking number. Since the order appears to have been delivered, even though I don't have it, and the tracking doesn't show where it was delivered, eBay says it can't refund me. In fact, it has closed my dispute and appeal. They also told me on Instagram that they can't do anything and won't respond to me further. I bought another printer from the same seller, and I'm afraid I'll be left without the money for both printers and the products. What would you do?
