I decided to get revision surgery, so I searched here and there, made a list of a few places, booked appointments, and went for consultations! I booked three places: ㅅㅅ, ㄱㄴ, and ㅈㅇㅈㅇ, but maybe because I booked in February, it took some time until the consultations.
At ㄱㄴ, even though I had an appointment, I waited almost 1 hour until the consultation, while at ㅅㅅ and ㅈㅇㅈㅇ, I had the consultations relatively quickly.
At all of them, I had the first consultation with the consultant and the second consultation with the director, and none of them charged a separate consultation fee! At all three places, the directors explained things well and answered my questions well too.
