Once the bill installment application is approved, it cannot be revoked, nor can the installment amount and the number of installments be changed. The outstanding installment funds in a successful bill installment business need to be paid off in advance. If necessary, you can call our credit card customer service hotline to apply. After the application is approved, the unpaid principal and handling fee will be settled in one lump sum, and the bill amount will be paid in one lump sum. (The business card has no installment business)
