There are a lot of deceptive things now, and it seems that there is little hope for complaints. If you really want to, contact the person who was cheated with you. The more, the better. You should know more about their cheating. Let's give the questions to the local education department, the letters and visits department and the local newspapers and periodicals to see what the situation is like. You're afraid of being alone and no one will pay attention to you. Speak louder and report the problem to the relevant departments legally and reasonably.
