Good day

I have made a reservation on the bookings.com website that stated last room at this price. The booking was for 2 adult 2 nights at R1700. The moment I furnished my credit card details I received an email confirming the reservation for 1 adult 2 nights at R3400. This is now a non refundable reservation for any cancellation. This is totally misleading. I have responded to booking.com immediately because my booking is for the 23 June 2024 and I urgently await their reply
