SHEIN Order Cancellation Request Before Shipment

Today I placed an order on the US Shein platform but I realized afterward that I do not need the items I ordered. I would like to cancel this order as soon as possible and receive a full refund of the amount paid. I have not yet tried to cancel the order or request a refund through the Shein app or website, and I am sharing my request here so that my order can be cancelled before it is processed or shipped. I kindly ask you to cancel my order placed today and refund my payment to the original payment method as soon as possible.
