I want to warn people not to do harm to their health

I want to warn people not to do harm to their health. Avoid this place, don't do anything there. You will not only lose money, but also your health. They take money in advance as soon as you give it, you are all in a trap. They constantly lie. They promise that everything will be fine, but you get crowns that crack and fall out. Implants that are twisted crookedly. And all you get is pain and stress, don't go there. I am looking for people who have suffered from them to file a class action lawsuit.
