You can find the relevant media department, or the tattoo training institution itself, and then you can find the consumer association, so if you want the tattoo training institution to make some complaints, you can find these departments to make complaints.

For example, if you look for the media department, you will look for the media to expose some of their behaviors, and then achieve the effect of a complaint. Because exposure can make training institutions make relevant claims or other relevant measures, media exposure is also a very effective means.

Then it is also a way to complain back to one of his own departments, because if his organization has problems, you can complain to his relevant person in charge, and then the third way is the consumer association, because you are a customer who consumes there, and then if there are problems, you can make some complaints related to consumers.
