Sir Ganga Ram Hospital — No Service from nurse station

I am currently in the hospital. The night shift people are great. But the people who come in in the morning about 8ish( not sure of shift start time), are a horrendous lot. Today I have asked for a wardboy to be sent with a urine pot. That was 48 minutes ago. I rang the bell. They silenced it at their station. That was 12 minutes ago.
Yesterday the senior nurse was hell bent on changing the sheets in spite of my protests( I had just been operated upon and was in considerable pain. Also my shoulders are delicate and can be dislocated quite easily. But she paid no heed and I ultimately ended up with my shoulder dislocated.
This is my fourth operation in this hospital. But I have to say that I am thinking of a different hospital for my next two operations.
If this is the way they are treating a patient who has already spent about 20 lakhs in this hospital, and that too out of pocket and not from some insurance or anything, I am horrified to think about the patients who spend lesser amounts. I didn't feel the need till now but I will certainly be looking at other options for my future operations.
