Heartbroken about NH (Hospice agency ). Saw blood stained sheets, his bed was a plastic pad on top of a gurney. He is dehydrated. Advice?

My father is 93 , good health, only takes one med (for high blood pressure) .# weeks ago he fell and twisted his ankle and got very confused. Called 911 and they put him in restraints as he screamed in agony and asked what and who they were. I lost my mother 2 years ago,and she only wanted to die at home but was stuck in a NH for 2 months, I decided to try Hospice and she died 2 days later. So I live with Dad now, and our rescue cats. I saw him get delerious and he was treated like a criminal. Full restaraints, Haldol, no help for his leg. I wanted to get him home ASAP.. I thought of trying Hospice, but somehow my sister claimed to suddenly have found a POA and conveniently activated it. I got dad home after day 3 and the next day I find she has enrolled him in full on hospice for terminally ill (he is not, never given the 6 months or anything close). This agency began coming ,terrible and loud, I finally wanted to change agencies and suddenly they reported me to APS and said I would not buy a new bed, and sister claimed Dad had to be turned every two hours ..I know? Anyway they brought ambulance and took Dad 2 hours away to this hellhole. I could not find him for 4 days and do not understand how he is still alive..he is very banged up, black and blue and deep wounds, like a casualtfrim shrapnel. I am trying to get his UTI antibiotics to him which he has not had as well as thinking of ER for deep bed sores or wounds and delerious. This morning an emplyee came in shouting I better pay a month up front ,and then a big big woman began throwing my purse out of the room and forced me out the door while I was hand feeding dad. OMG! I am so terrified and heart broken. I could have stopped this tragedy of errors ..
