When a customer applies for a refund, how to deal with the withdrawal of the Meituan user?

If the customer applies for a refund, we can refund the order according to the customer's requirements. Of course, if my customer really wants to return the bill, he will definitely not ask us to return the bill to the customer. If so, the platform may also spoof you, so I deducted some money from you. It's best for customers to do it themselves.
