"lack of patient care"

I had hoped that bringing to the attention of the hospital that there was a lack of patient care when I called the Endoscopy department this would have been addressed .Astonishingly when I called again today I was told that there was not enough staff to be able to provide me with an appointment and consequently I had to leave the tel number for the second time in two weeks. It is a shamble and again I cannot pick from the drop down list as endoscopy is not there.
