1. Make sure that the payment information entered by parents is correct. Parents need to check whether the payment information is correct, including bank card number, account name and expiration date. If the information is incorrect, the payment may fail.
2. Check the network connection. If the parents' network connection is unstable or too slow, the payment may fail. Parents are advised to try to switch to other network environments, such as using traffic or trying to connect to other Wi-Fi networks.
3. Contact relevant personnel. If the above methods can't solve the problem, parents are advised to contact the customer service staff of Ai Jia Municipal Committee or relevant technical support staff to find out the specific reasons for the payment problem and seek their help.
Generally speaking, parents need to stay calm and follow the steps. If you encounter problems, you need to communicate with the platform customer service or related personnel in time to solve the problems as soon as possible.
