Booking.com Reservation Issue: Payment Deducted, No Booking Confirmation

Yesterday, as usual, I made a reservation on Booking.com for Granada Luxury Hotel. The required amount was immediately deducted from my card for the reservation, but I did not receive any booking details. It seems like Booking.com doesn't exist; there is no phone number, and I can't communicate with them. The hotel says they have no record of my reservation. Where can I file a complaint?
