Booking.com is a ****

I paid for an honest service for accomdation on Booking.com (R15,040)... the host went completely silent when I had to arrange check in and I had to call Booking.com as I could not get a hold of them. Booking.com then informed that the host said they couldn’t accommodate me, and that I had to pay for another accomodation because I was only going to get my refund within 7 days from 17 Feb 2023. Now Booking.con are asking me to ask my bank to launch an investigation because thier service provider could not provide a service I paid for. It has been over 16 days and my emails and calls get ignored by Booking.com. I want my money and I will never use this service again. Proclaims to provide access to accomodation but cannot follow through after customers pay. My reference is ***
