What's the matter with the lawyer's delay in assisting in filing the case?

If you are sure that your friend is slightly injured, you can go to the court filing hall to apply for filing. There are judges in the filing window of each court to guide you how to go through the formalities. If the case is filed, the lawyer will be unreliable. You can complain to the local judicial bureau or bar association and ask him to refund the agency fee. If the court says that the case cannot be filed, then the lawyer is not wrong.
