Failure to respond to complaint on bad attitude

Was admitted at Alberlito in BALLITO. I complained to the management about their student nurse ( Thuli) at medical ward for denying me to have visitors more than 2 where as other patients were allowed to have 3,4 and 5 visitors at once. I felt I was being discriminated as I was the only black in the ward and possible it would have been improper for her to do same to whites and Indian. I was then moved in a room temperature controlled Isolated room she repeated the same. I confronted her and we argued and she told me she is doing it because I'm in isolation and she does not care I can report her. I reported to management she was made to apologise Immediately after management left she started discussing the matter with her pals next to my open door so that I can hear them.She told them how she acted apologetic yet she was not, they started reading loud my medical file and diagnosis making joke of the matter and share their wish that I don't make it. I was a bit disturbed. Me& my Dr reported the matter again to Unit and Hospital management so that disciplinary can take place against unprofessional nurses. Hospital promised to take further steps but nothing has been done to date
