Rude contact center staff - got a message saying my appointment had been moved to a time and date I couldn't do. Called up and the operator said they might possibly be able to move it to the next day but couldn't confirm a time (helpful) and got really impatient with me when I was trying to clarify (Korean isn't my first language, as she was surely aware). Then the only appointment they could offer in the next 6 weeks is at an inconvenient time and 2+ weeks away. Not impressed.

There is an English person for taking appointment and call but there is not a single translator for you in the hospital . As a foreigner it’s so hard to talk with the doctor
