Shameful and shocking service from Booking.com

Made a booking via Booking.com in May 2024 at Manzini Chalets Marloth Park via the booking platform. Booking no: ***. It was confirmed and pin was provided. Payment was taken from my Credit Card on 17 July 2024 and we proceeded t travel to the venue for accommodation on 3 August 2024. Whilst nearing the venue I tried contacting the venue on the number supp**** via the booking confirmation but could not reach the venue notwithstanding confirming time of arrival. Upon arrival I noted that the venue was closed. As I stayed there before, I was aware that the contact person resided opposite the venue and proceeded to the premises and knocked on her door. She opened and was surprised that yet another person advised her that they had booked the venue and that Booking.com never advised that the venue had been closed since April 2024 due to the owner passing. I immediately called Booking.com and spoke to a Ferris who advised that he had to contact the venue to get a response and continued with the approach notwithstanding the fact that I told him that the venue is closed, the owner is dead and that he should refund me as it was late and that I had to urgently find alternative accommodation. Ferris undertook to phone me back after I confirmed that he had my number which should be reflecting in his call log. I did not get any call and when I arrived back home a week later, noted that I had received an e-mail on the day offering some alternatives. This was not the request to Ferris as I advised that I am on leave and did not have my laptop with me. I had also not received a refund nor have they responded to any of my several e-mails to the customer care line. It is shocking that until date, I have not managed to make any contact, one holds on to international calls to the Netherlands and get cut off after 20 minutes, nor have they refunded me. They should not be allowed to operate in the country if that is the manner in which they disregard clients who book accommodation via them and not being advised that there are issues with the venues. I have been using them for years and is shocked at the treatments, lack of service and commitment and will slate them where I can so as to avoid other unsuspecting clients dealing with them without knowing what they are in for if they fall victim of being conned by this booking company.
