Call the customer service hotline of Guangfa Credit Card Center at 95508, and then switch to manual operation, requesting cancellation. The customer service will say that someone will contact you in a few days. Be firm and cancel when the time comes. It should be noted that the money in your credit card has just been repaid. You can't have extra money, and you can't pay less, even a few cents, just right. Otherwise, I don't know when the credit card will charge you an account management fee. Even if it is cancelled, there will be a lot of interest at that time.
