BOOKING.COM IS REFUSING TO REFUND MY MONEY FR BOOKING THEY DID NOT MAKE

I made a booking on Booking.com for a hotel and made the payment. After the payment went through, I did not receive any confirmation. Then emailed Booking.com only to be told that the booking had not gone through and but they will not be able to refund me my money immediately, they will only be able to do that in 21 days. In the mean time I was supposed to travel and I have no booking. They are refusing to do an immediate transfer of my money. My ref number is 1b3232d9-9eba-4bd0-b726-b4fdea687a7c. Don't ever make a payment on Booking.com. Rather make the payment at the establishment so that if they don't confirm your booking at least you still have your money and you can make other arrangements. Their customer care is the worst I have seen. I can't even call them because I have no booking reference number which they couldn't generate even after taking my money. I have never seen such worst service. PLEASE JUST REFUND MY MONEY SO THAT I CAN MAKE ANOTHER BOOKING.
