Booking.com Charged £616.99 but Never Sent My Flight Confirmation

Last night I tried to book a flight from Jamaica to London Gatwick for 4 December through Booking.com. The payment of £616.99 was taken from my bank account this morning and the transaction description in my bank statement clearly shows “Booking.com”. However, I never received any booking confirmation or reference number. Since then I have been unable to get in touch with the company. The phone number I have, 020461779**, does not allow me to reach anyone, and when I try to contact Booking.com through their website or app it is very difficult to get support or find my supposed booking, because I have no reference number to enter. My bank has confirmed that the payment has left my account and advised me to contact you. I am therefore asking Booking.com either to locate this payment, issue my flight booking from Jamaica to Gatwick on 4 December as intended, and send me a proper confirmation, or otherwise clearly explain what has happened to this £616.99 transaction.
