"Common courtesy wasn't provided"

My mother is not a frequent hospital visitor. As in her mid 70s she's been lucky enough to avoid it. However due to a recent spell of ill health her GP referred her to urgent care, she has lost 12 kilo weight inside a year. Her gait is unsteady as seen by doctors and nurses and she had no appetite at all, she hasn't eaten in more than a month. 

At first she was was on a trolley in ED. She was at this point waiting for an inpatient bed, I know these are very hard to get. Then she was moved to a bed and placed in a corridor. My very private mother did not deserve this and her family feel this was not at all the right place for anyone to be treated. 

Next morning I spoke to her and she said she had been seen by doctors but wasn't sure what was happening. I phoned the department to speak to the nurse looking after her, just before 9am. The receptionist said the nurse was very busy but would call me back. I said no problem and I left my name and phone number which was repeated back to me correctly. 

My mother then messaged to say she was being discharged. I hadn't yet spoken to the nurse and I had questions about how appropriate this discharge would be so I called back. I called back three times and each time got on hold on ED reception. Nobody answered. I sat on hold each time for around 20 mins or longer. The nurse didn't bother to phone me back either. Common courtesy costs nothing but still wasn't provided. 

I know the service is stretched but this has been a shambles. I had felt my mother should have been referred to dietitian and OT at least but no one did this. She's been told an appointment will be sent out. She's now at home with exactly the same symptoms she was admitted with and nothing has been done. 

As said I know beds are in short supply. To my knowledge, I know there are wards in other hospitals that are empty. Would it not occur to someone, that maybe these should be opened and staffed and then perhaps patients wouldn't have the indignity of being treated in a corridor without so much as a room divider for privacy? The lack of accountability in the trust management is astounding.
