The time it takes for Booking.com to process a refund depends on several factors, including the payment method used and the hotel's policies. In general, once Booking confirms approval of a refund, it may take 5 to 15 business days for the money to actually appear on the credit card or original payment method used by the customer.
It is important to note that some banks or credit card providers may take additional time to process your refund after Booking.com has issued your refund order. In rare cases, this process may take up to 30 days.
If the payment was made via another form, such as a bank transfer, the times may vary even more. In any case, it is advisable to check directly with your bank or payment provider to obtain the most accurate and up-to-date estimates on expected repayment times. If your refund is not received within the expected timeframe, you are advised to contact Booking.com customer service for further assistance and clarification.
