I sold a pair of Louis Vuitton shoes that are a size 39 that do equal a size 9, for sure. I put measurements of the bottom of the shoes (they're flats) in the auction and the buyer is swearing up and down that they aren't a true 9 and they don't fit her and she wants a full refund. I told her that I normally don't accept refunds, especially because of size discrepancies since I put the measurement on there. When I do accept refunds, I only accept 75% BUT I said because it's the holidays I'd do an 85% refund. SHE SAID ITS NOT ACCEPTABLE. She told me that a size 40 is a size 9 after googling it. Depending on the shoe and the brand, it could be totally different. I have a pair of Jessica Simpson shoes that are a size 38 european and an 8 US. What do I say? She says, "It appears that the auction info was inaccurate and as long as that info is provided, anyone who buys the shoe expecting it to fit a size 9, will be disappointed. Based on this inaccuracy, I'd like a full refund because I would never have bid if I had known of this auction's error. Since I will have to return the shoes, I will have to pay for shipping twice. Your consideration is appreciated." I'm size 8 and I wear 38 in these shoes... my sister is a true 9 and wears a 39, these were her shoes. The buyer says they don't fit and a partial refund isn't acceptable. am I wrong here? What do I do in regards for a refund?
