How to apply for a takeaway refund from the US Mission?

At present, the process of the US group's take-out refund is generally like this. First, you can apply for a refund on the website. If the merchant refuses, you can complain on the webpage. After complaining for a period of time (ranging from a few minutes to dozens of minutes), Meituan customer service will contact you to understand the situation. If your refund is justified, Meituan customer service will negotiate with you and the merchants to give you a refund; If you and the merchants hold their own opinions and have their own reasons, Meituan will settle for the second best and propose a refund in the form of Meituan prepaid card (prepaid to your Meituan account, except for cash withdrawal, any purchase you make on Meituan can be paid); If the complainant is completely unreasonable, Meituan will also refuse to accept your complaint. Back to the above, if you complain on your own website, the customer service can't be contacted, or you can't wait, then you can call the customer service of Meituan directly and let your complaint be handled manually. Please remember to use the number you ordered to make a manual complaint. I feel that it is more likely to successfully dock with customer service. I hope I can answer your question.
