SHEIN Has Not Delivered My Order or Processed a Refund

I placed an order on Shein on 21 July that included a perfume set and a NeeDoh squishy box. The estimated delivery window shown at the time of purchase was between 29 July and 3 August, and the shipping address is in Spalding, England. Despite this time frame having passed, the order status in the app still shows as “departed from facility” and has not progressed further. In addition, when I click on the products in my order details, it says that the items have been removed, which makes the situation even more confusing, as I do not know whether they are still being sent or not. Since the promised delivery dates have been exceeded and the items are now marked as removed in the app, I request a full refund for this order without any deductions. I would like this issue to be resolved as soon as possible and to be informed clearly about the status of my order and refund.
