If it is a drug quality problem, you can complain to the Food and Drug Administration. If it is a drug price problem, please complain to the price bureau. If you buy other items in a pharmacy, you can complain to the Industrial and Commercial Bureau.
If it is a medical insurance card problem, you can complain to the Labor Insurance Bureau, and if it is a medical problem, you can complain to the Health Bureau.
In addition, if you don't know which department to complain to, I suggest you complain directly to the local Consumer Council.
