hello. When you make a return by using a credit card, you can contact the merchant to operate 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). Credit card refund details can be inquired in the following ways (the refund details are the amount expressed in negative numbers): 1. Online banking inquiry, log in to the online banking popular version/professional version, and click Account Management-Billing Inquiry or Billing Inquiry. Please click:/cmbbank _ genshell/ui/genshellpc/login/login.aspx? FJID=VReeRQ:qI8M_； Log on to online banking. 2. Self-service voice inquiry: Call the credit card customer service hotline, verify your identity, press 1, and then press 5 to enter the "Billing and Transaction Details of the Last Year". Or press 1 and then press 3 to enter "Unbilled Bill".
