If it is negotiated voluntarily by both parties, it is valid! After all, this is also the basis of their commitment to you. Therefore, it is effective. If there is any problem, it is recommended to complain to the Health Bureau!

When it comes to medical disputes, it is better to complain directly to the local county health bureau, because as a local plastic surgery hospital, its competent department is the health bureau (Health Planning Bureau).

Therefore, you should bring the relevant agreement and refund promise signed with the hospital (providing the relevant basis for the hospital's promise), complain to the local health department and ask for help.

I hope my answer can help you. Hope to adopt! ! !
