Booking.com Charged Me But Never Sent My Philippine Airlines Ticket

I booked a flight through Booking.com with Philippine Airlines from Singapore (SIN) to Manila (MNL) for travel on 28 May 2026. I completed the reservation and payment on 13 May 2026, and a total of 21,844 was charged for this flight. The reservation is under the name Jenny Patung***, and I have the reference CAR260512184707007 as proof of the booking. Despite the payment being successfully processed, I have not received my flight ticket by email. I made the booking using the email address jpatungan***@gmail.com and I have carefully checked my inbox, spam, and junk folders, as well as other email accounts I use, but there is still no ticket or proper confirmation email. Because of this, I am currently unable to access my ticket details or be sure that my reservation is valid with the airline. I have tried to reach Booking.com customer service regarding this issue, but I have not received any response so far, which is increasing my concern as the travel date is approaching. I request that my flight ticket and full booking confirmation be sent immediately to my email address, or that I be provided with a clear solution so I can take this flight without any problems. If the ticket cannot be issued for any reason, I expect a full refund of the 21,844 I paid without any deductions.
