"Dreadful contact experience"

Although I fully appreciate how busy you all are, I have been trying to contact the nurse responsible for looking after my relative for 3 days, without success. It was impossible to get anyone to answer the first telephone number I was given (31 redials with ringing then cut-off without answer). Eventually given another number for AMU - where the Ward Clerks would answer, only to be transferred to the nurses station, where the phone would ring out without answer (apart from one occasion when I was told the nurse was too busy to talk to me!!!!). How on earth am I supposed to find out how my relative is, and whether they are likely to survive or not. It is so very frustrating and worrying to be a relative in this position.
