Unhappy patient

I'm wasn't happy with the service of which it wasn't the first time I came and I joined the que like everyone I see they were keep calling people even the one came after me then I decided to ask after asking they sent 3 of Us to the African doctor ,the same Dr I mentioned before that I'm not comfortable with him because every time he is giving injection not even one day I consulted with him he is not giving injection, and even told them no I don't want to see him instead they laughed those reception ladies ,I felt more ****** because people came after me were colored and Indians and definitely they had no appointments ,can we be treated the same way and the Dr must assist us and pay attention on patients as a patient I'm expected to be examined correctly
