How to complain about the salespersons of China Mobile and open their business to consumers in disguise?

In which business hall did you do business? Because you haven't seen her job number, you can go to the mobile business hall where the salesperson is located and ask the manager to complain about her. There is nothing to complain about other methods. If you call 10086 and you don't know her job number, you can't complain. You can only find their manager in their business hall.
