Booking.com – Refund for Xiamen Airlines ticket

Description of Events:

On February 2, 2024, I purchased a service from the merchant.

On April 7, 2024, I requested a date change, and on April 10, 2024, the merchant charged me for the change to a ticket scheduled for April 17. I later canceled this transaction and purchased another ticket.

On May 1, 2024, the merchant processed a partial refund of 13,460.66 due to a canceled service not provided.

On December 2, 2024, the Xiamen Airlines committed in writing to refund the remaining amount for the canceled service not provided, requesting an account outside of Mexico. In 2025 I provided an account in China, the Xiamen Airlines informed me that the transfer had been rejected without supporting documentation.

Despite more than two weeks having passed since that communication, the refund has not been credited.
