ebuygoodshome on eBay said they were going to refund ALL my money but they tricked.me into paying for the return postage and telling me they would reimburse me for the cost, which was a lie. They refunded my money on Aug 7, 2024, but not the postage. I showed them the receipt and tracking number, which did little good, because they had no intention of refunding my postage expense. That was almost 4 months ago. I have sent them numerous messages and they ignore all of them. eBay won't help because, as far as they know, my money was refunded.
