when you make a refund by credit card, you can contact the merchant for a credit card refund (the money can be directly returned to the credit card). The entry time depends on the merchant's return operation method, and the general time limit is about 2-3 days (the monthly repayment is still subject to the actual account situation).

You can use Alipay for inquiry, and you can also use official website of China Merchants Bank for inquiry: log in to China Merchants Bank Credit Card official website (/), click "Online Banking Login" on the right, enter your ID number, inquiry password and additional code, and then click "Account Management"-"Account Inquiry" in the horizontal menu above.
