How to handle the installment SMS of Pudong Development Credit Card?

It can be divided into two stages: 1 stage payment supported by merchants and 1 stage payment supported by banks.

Ask the merchant first, if not, shop first, and then call the bank to apply for installment payment before the current interest-free repayment date. Installments will pay different fees. Then the installment deducted from each installment is equal to the consumption of the current month. Pay off before the repayment date of the current month, without interest. . . .

Yeah, give it to me. . .
