Anyone have experience at Yanhee or Kasemrat Prachachuen hospitals for gen med?

Unfortunately the staff witheld notice of social security dropping my present hospital Paolo while they translated names into English. I was notified Friday and have to make a decision by tomorrow Monday.

Only hospitals relatively close by open for enrollment are Yanhee and Kasemrat Prachachuen hospitals.  The rest were either near Pathum Thani, Samut Prakan, Bagna areas--way to far. 

Have only heard about Yanhee for gender change or other plastic surgery- neither of which are of interest to me.

Not even sure if there is a minimum amount of time you are still covered under old hospital when they give notice to quit program or if you are cut off day at the end of the month.
