How to complain about CICC's online account opening and stock commission fraud?

You can complain to the supervision and management department, such as the CSRC. However, I'm afraid this won't work. The best way is to ask for a reduction in commission directly, or to open an account with another company. After all, there are many accounts that can be opened now, and there are many companies that can open low commissions. There's no one here, so there's room for someone.
