The service was okay but the queue was terrible. I came and took the queue number at 16:51 and was only called for registration at 19 (that was because I reported and complained) and it turned out that my number had been passed by two new numbers (I was number 2178, but who knows what time, the number was repeated from 2001). Then the registration system error, I have to wait until 19:20. After that enter the examination process room. Then until now (20.15) still waiting for the doctor who visited. He said 30 minutes but from 19.30 until now also has not been seen at all. Please improve the administration flow and the availability of doctors. Because the officers are actually very friendly. Thanks.
