Booking.com Refuses $301 Refund Approved by Property Host

I made a booking through Booking.com at The Workshop for August 16–20, totaling $602 (Reservation #6758.314.576). On August 15, I had to cancel the reservation due to an emergency and submitted a refund request through the system.

The property owner explicitly confirmed via in-app messaging that they agreed to a 50% refund. Despite this, Booking.com deducted 100% of the reservation cost and issued no refund at all. Withholding this money despite the host's clear approval for a 50% refund has caused significant hardship and directly contradicts what was agreed upon.

Following this issue, I have messaged customer service repeatedly via in-app support over the past three days, but I have received zero response. Since the phone support line in Turkey is effectively unresponsive, in-app messaging is my only avenue to report this, and the issue remains completely unresolved.

I demand that the 50% refund ($301) approved by the host be credited to my account as soon as possible, along with a detailed breakdown of deductions and a formal written explanation regarding this total lack of communication.
