Booking.com host scam - I lost $3,100, Booking customer service literally told me the wire was fine before I sent it

Warning for other Booking.com users. In April I booked a Paris apartment. The "host" messaged me through Booking's own chat asking to prepay by international wire to an IBAN. Because that felt off, I contacted Booking customer service to verify before sending money. The Booking CS agent replied in writing through the Booking Assistant: "your booking is being facilitated directly by the property... as part of their policy, they require a prepayment check to confirm your ability to pay."

So I sent the wire. $3,100+ to an Italian Poste Italiane account in a personal name (the apartment was in Paris). Hours after it cleared, the "host" cancelled the booking. Days later Booking emailed me admitting the property "no longer operates on our platforms" and committed in writing to a full refund within 14 days. That deadline came and went. When I followed up they rejected my Chase wire documents claiming they didn't show "transaction date, amount, or currency" - all three are printed on page 1.

So far I've filed an FBI IC3 complaint, sent a formal escalation to the CEO, and Chase confirmed the wire can't be recalled. Anyone gotten Booking to actually pay out on this pattern? What else can I do or there is no hope?

If your "host" on Booking.com asks for a wire transfer: stop. The partner account is compromised. Don't trust Booking CS to catch it either, I did and it cost me $3,000.
