The credit card can be paid off in one lump sum, but if the credit card holder needs to pay off in one lump sum after installment, he needs to contact the bank customer service staff in advance to terminate the installment.

No matter what kind of prepayment, the fees already paid will not be refunded, and the remaining fees will be set by each institution.

Credit card one-time repayment usually means that the user changes the repayment plan halfway after choosing the credit card installment. The user wants to pay off the installment arrears in advance, so he chooses one-time repayment.
