(ASL summary in link above)
Have you ever experienced discrimination because you are a deaf or hard of hearing person? The NAD strongly encourages you to file a complaint so that you may be able to resolve the problem as well as raise awareness. The first step is to identify who discriminated against you and where the discrimination happened. This information will determine where you should file a complaint.
See https://www.nad.org/resources/how-to-file-a-complaint/ for more info and links for various issues. Each category has asl video also.
