Order not received

On May 12, 2019, I order a FrSky R9MM Long Range Receiver (SKU: 9236000157-0). The item has been shipped via Specific Shipping - Semi-Trackable Express Air Mail (Expedited) 1g - 100g. The article seems to be missing and the chances of getting the RX are very low. The last status of the shipment tracking is: May 24, 2019, 01:11 pm, The consignment has left the origin border point, Asendia HK, Asendia Hong Kong. My conversation with a HobbyKing custom service representative resulted in "This is out of HobbyKings responsibility and up to the customer to follow up".I think this is the last article I ordered from HobbyKing.
