"Poor service"

I am so disappointed, yesterday I brought my mother as a transfer from the GP,she is known diabetic, hypertension, kidney impairment and has been diagnosed with gallstones by the private scan which was the main reason she was transferred. When we got to the hospital we had to wait from10h30-15h30 to get the file and she was only seen after 16h00 in casualty by few Drs who were busy focusing on reading her file and the scan& blood results we brought with us instead of examining her,then on Dr took bloods from her and was discharged thereafter without waiting for the blood results.A sister told me she has been discharged with TTO which I should fetch the following day because pharmacy was already closed. When I asked one of the nurses what TTO Dr wrote he told me it was panado&buscopan which were also written up as a stat dose which she never had.now am sitting here at home with her in so much pain and no painkillers helping.How I wish someone explained to me what to do next.
