I've already sent an email to the customer service in this hospital.. But, I came in not too long ago, and all of the nurses belittled me and were saying things towards me till the point I started crying and left, for what? I wasn't wasting any of their time, I was on time and had a good reason to be there so not sure why they kept making nasty comments and remarks towards me.
