How to refund the price difference between the merchants of the US Mission?

The steps for Meituan merchants to refund the price difference are as follows: first, enter Meituan's interface, click on the order, then select the order that needs to be refunded, and finally enter the interface and click to apply for a refund.

If there is a price difference, if the Meituan merchants do not solve it, they can directly call the official telephone number of Meituan for complaint feedback, truthfully provide the store name, address, telephone number and other information of the respondent in detail, and explain the reasons for reporting the complaint.
