BOOKING.COM REFUSE REFUND FOR CLOSED ESTABLISHMENT

I made a booking through booking.com for CASA ***** in Kalk Bay. booking was for 33rd wedding anniversary on 15 Feb made booking and payment on 28 December 2024 - well in advance. Came time for my stay, I phoned Casa *****. Phoned 10 x - no answer. eventually saw on their website that they are closed. And upon further investigation, established that they have been closed since May 2024. Booking.com took my money on 28 December - SEVEN MONTHS after Casa closed. Abd now they refuse to refund me R3 430.35 - a lot of money that I cannot afford to lose. I have phoned Booking.com - MANY TIMES. I have emailed Booking.com - MANY TIMES. No success. I am desperate and don't know what to do next. It has now been more than a month. I never expected a reputable, international platform to allow bookings and take payment for an establishment that is closed. AND THEN REFUSE TO REFUND THE CLIENT. TRULY SHOCKING. BE AWARE - Booking.com cannot be trusted.
