What does it mean to remind the customer service of WeChat payment that the payment amount is wrong?

Wechat payment customer service reminds that the wrong payment refers to the wrong amount when paying.

When users use WeChat to pay, if the amount paid does not match the actual amount to be paid, WeChat payment customer service will remind users to pay the wrong amount. This may be caused by the wrong amount entered by the user or a system error. Users can reconfirm the payment amount and make corrections according to the customer service reminder.
