Let me start by saying I have purchased a handful of times from StockX and have had slight issues here and there, none that made me write a review here and everywhere else, to raise awareness of the shady/poor customer service business StockX runs. They stand behind the fact they are a mere re-seller and do not hold stock on product to "wash their hands" in making the sale 99% final, and up to their judgement to help or not their customers. I purchased a pair of sneakers for a friend on 5/26/20, to my bad luck the sneaker order went out with the wrong shoe size. This was due to a faulty app process during checkout, after selecting the shoe and the size (8), clicking on the buy now button, it defaulted back to size 10.5, which was the very last size shoe I had purchased (on a different date). I have contacted StockX customer support multiple times, through their contact site, through Twitter, and all I get is a dismissive email saying in other words, the sale is final and nothing can be done. The customer support rep says the only option is RE-SELLING the shoes on their site, to their advantage and additional profit. I have an email from their customer support saying they apologize the app is faulty, but still they can't help me further, mentioning again I can re-sell them in their website... This is absolutely no way to treat a customer, to build loyalty or to just conduct business, zero solidarity and "owning" the situation. Pasting the customer support response on my third attempt to resolve the issue, and explaining exactly what I say above "Hey there Gianmaria, Thanks for reaching out to me! It sounds like the product page selected size 10.5 as this was the size from previous purchases. Please be careful when looking at the product page. I am sorry to see that you want to cancel your recently confirmed order on StockX (#12141238). ?Unfortunately, when a 'Bid' and 'Ask' match, the order is confirmed and no longer can be canceled. The integrity of the marketplace depends on it. ?The good news is that once you receive your purchase, you can always resell it on StockX. ?I apologize for any inconvenience this may cause you and please let me know if you need anything else in the future. Sincerely, Romero"
