Should I take this further?

Hi there @onemargie , so far the story is this. The morning after the fall, I asked to see the Patient Representative Officer. She came to my bed a couple of hours later, when I told her what had happened. She expressed her concern and said that she would go and look at the drain herself, and would return later. (She did jot down things in a note book as we spoke). Later that afternoon, she returned looking very frazzled. She said that she had seen the drain and had the called other staff to go with her to do the same. Some sort of Maintenance person as well as I believe someone to do with Health and Safety. Apparently, one of these other persons made a comment along the lines of "Oh my word, this is an accident waiting to happen...it's a miracle this hasn't happened before". Instant enquiries were then made about replacing this drain cover, but they were told it would take three weeks to arrive. The decision was then made to spray the cover yellow in the meantime, to make it more visible.I then asked if I had to write down my complaint, and she said that given my pain (excruciating), it was not necessary, as she had all the details written down herself. After getting home, five days later, the initial shock had worn off and I attempted to get something more out of Management regarding this event. Nobody from further up the food chain ever visited me, sent a card, or even a miserable carnation stuffed into an empty Coke bottle, by way of an apology for the hospital's neglect of my safety. As it happens, very bad and rude treatment by one (only one mind you), of their nurses pushed me over the edge. She had treated me like some sort of nuisance who was taking up a valuable bed which was need by other patients far more ill than myself. I pointed out to her that I wouldn't have been in her precious bed had it not been for the dangerous drain in her hospital. I took that matter further to the Unit Manager and I believe she was "counselled". I have subsequently tried to get the names or positions of these other persons who went with her to see the drain, specifically the one who made the comment, but have been told that that was not possible. I have been told that they have 35 days to respond to the complaint, and that basically, I should just sit in the corner like a good girl, and shut up until that time. Thirty five days for the steam to build up...good luck to them when it eventually escapes!!
