Booking.com is a ****

On the 2nd of January 2024 We booked a flight from cape town to OR Tambo international airport, we paid R28 111,51 for 7 people 4 adults and 3 children. When we got to the airport we were told this flight doesnt exist and we were ****med. We tried to inform the booking.com but they were not able to assist us and we cannot be refunded.
