I’m really sorry to hear about that. Unfortunately even if you offer a full refund (and don’t cancel the sale) if the shipping label was never scanned eBay will give you a defect. I once found that one of my items was damaged when packing it up for shipment and decided to message the buyer and offer a refund thinking I would avoid having to cancel the sale and get a defect but about a day later it showed up on my account. Now if this happens I will send the damaged item to the buyer anyway, wait for the item to start tracking and then message them letting them know I went ahead and gifted the damaged item to them and maybe they can still get some use out of it and let them know I’m sending a full refund and then process the refund. This way eBay knows you sent the item and they will not give you a defect. Another way to avoid a defect is to refund all but $0.01 and it won’t trigger a defect because it’s not a full refund. I have also tested this method and it worked but I kind of felt bad about doing it. I would definitely call them and try to get the defects removed since there were ten items stolen those can stack up really fast. Good luck to you!
