Ctrip's order has not been cancelled. Why is there an inexplicable refund?

First of all, you received a refund message without canceling the order. You should log in to your account to see if your recent order status is still normal, which may be caused by the cancellation of the order by the platform or the agent.

If there is nothing unusual in the order status, then check the order amount placed some time ago to see if Ctrip or the agent made a mistake and refunded the previously completed order.

If the order status is ok, there is a great possibility of Ctrip's misoperation. They just haven't found it yet.
