Amazon Order Disappeared from Account – Item Not Delivered

I placed an order on Amazon Australia on 01/07/2026 for “Xstrong Egg Tart Molds 12PCS” with the order number 503-7109604-8809415, for a total of $37.55. According to the Amazon order tracking screen, the item shows as shipped, but the order has now disappeared from my “Your Orders” section and I have not received the product. I can see from my Amazon records and emails that the purchase was processed, yet I am unable to follow up on the delivery because the order no longer appears in my account. This situation leaves me without the product and without a clear way to track or resolve the delivery. I request that this order be investigated, my order be restored in my account and the “Xstrong Egg Tart Molds 12PCS” be either delivered to me as originally promised or that a full refund of $37.55 be issued to my payment method as soon as possible.
