The refund rule of Dapeng Education is that if the registration is successful, the class will be fully refunded unconditionally within 24 hours. There is no reason to apply for a refund within 7 natural days of a successful course. Dapeng Education deducts 8% of the comprehensive management fee. If you apply for a refund within 90 natural days of the success of the course, you need to deduct not only 8% of the comprehensive management fee, but also the course fee according to the number of days. Two years is obviously much longer than 90 natural days.
