Hi I’m struggling to request a refund for this product. I really like the chair but it has clearly been used beforehand. There are marks and chips on the chair and it hasn’t come with enough screws to put together. One part doesn’t even fit the chair so I can’t put it  together. I’d really like some help please how I can get a refund and a replacement chair sent out The delivery was very quick which was great but I would expect more from a chair of this price. Thank you
