"No compassion"

My dad was taken to hospital by ambulance having fallen, he is a diabetic and had gone into a diabetic coma having not ate for two days as he was unable to swallow. He was on the high dependency ward he was then moved to 3b. I visited him just before he was moved and the nurse told us he was getting moved so to get ready as they would be being moved now. She took his medication and he asked her why and where she was taking it, she was extremely rude and arguementive with her answer. Why is she arguing with an elderly confused and scared man. We sat ready to go but the nurse was very rude to him when he asked why she would not let him have some cream that another nurse had said he could have. She then continued to chat up the porter for 30 minutes, in our ear shot. Then when she had eventually realised what she was supposed to be doing. On the way up to the ward they didn't talk to him but carried on talking to each other. Now my dad is 83, confused and scared, deaf and has limited sight and was not being told anything, only for the fact I was with him he wouldn't of known anything. I was with him on the new ward for an hour and at no point did anyone come in to see him. He had no pillow or blanket on his bed and he was cold. I went back for the evening visiting and still no blanket. He went all through the night with no pillow or blanket as he was only given it the next morning. He asked a nurse the night before, she went off duty not having got it for him. During the evening visit he started to feel like he wanted to vomit, so my son went to get him a bowl, at no point did a nurse come to see if he was ok. When he was on the HEC he was given 2 antibiotics. When moved to 3b he was given one tablet when he questioned it she said no its just one tablet I don't know why you were given two. Then she looked at his notes and she said oh yer it is two. I am trusting these people to look after him and they are making mistakes like this. This is heart breaking for my family, his tablets are left on the side for him to take and when I go in his tablets are still there and I have to remind him to take them. Someone came to see him about his swallowing and she was giving him biscuits (he is a diabetic) she said there was nothing wrong with his swallowing and as she walked away he took one of his tablets and proceeded to choke on it. The place is a joke, he was begging me to take him home. This is some of the stuff I have witnessed what is happening when I am not there.
