There are two ways to automatically installment credit cards. First, the credit card itself is an installment card, which is characterized by installment. When the consumption is full, it will be phased. The solution to this situation is to change the card, and the ordinary card used at ordinary times will not be automatically phased. If you can't change your card immediately, you can call customer service to see if you can increase the minimum installment amount or other methods. Second, ordinary credit cards are equipped with automatic installment function, which is relatively simple. Call customer service to solve it. You can apply to turn off the automatic installment function, or you can apply to cancel the installment and return the installment fee.
