Is it suitable for children to learn programming? How to treat a family called Tongcheng Tongmei?

Dana's childlike innocence gave me a good impression at first. I thought that the management and service of big companies should be more professional, but after in-depth communication, I found that the service attitude was very problematic. I have complained to a customer service staff of Tongcheng Tongmei before, and the service attitude is extremely poor. Just put forward some reasonable suggestions and opinions, and kicked me out of the VIP WeChat exchange group without any communication with me. The attitude is extremely bad, and there is no respect for the bottom line of customers. I can't say anything they don't want to hear. The following is a conversation between me and another parent.
