Baffled: Recived item quicky and nicely packaged but shoes were different sizes! I don't have different sized feet, so I emailed the seller and asked if they had accidentally sent two different size shoes. Seller did not respond to my request, nor try to make things right. I'm giving this seller a "Neutral" instead of a Negative because I'm trusting in best intentions here, but, yeah, what an unfortunate surprise. Seller, I'd love to hear any response. Was this simply a mistake?
