Seller says our FR10 and controller cable reached the agent. Agent says awaiting receipt under another reference. Nobody will say where the crate actually is.
Put both references, the packing list and crate-label photo into one request to both contacts. Ask them to match the physical crate to the handover and receiving records, not explain their own reference again.
Then ask the seller for that receipt with the crate identifier visible. They arranged the claimed handover; they should be able to help trace it beyond repeating handed over.
