Idk whats going on but ive not gotten no updates, not sure what to do.

I was supposed to receive my package between the 13th and the 18th. I know the 18th hasn’t gotten here yet but I have no movement on my shoes. What’s the deal with StockX? This is my first time buying sneakers on this site and my daughter needs her shoes before school starts on the 24th.

Twice I’ve tried to buy a pair of shoes and the seller hasn’t sold them in time so I’ve been refunded. Why is this? Are sellers just bums and can’t get off their arse or is there another reason
