No basic need for us

Im utterly disappointed in the service,my brother was in an emergency ward for 3 days sitting on a chair,when he was attended to the doctor advised him he defaulted on meds assumption,but this was not the case,he was taking his meds,when he consumed it he throw it up, So its not that he defaulted on the meds his body couldn't consume it.So we he rushed himself to the hospital and stayed there for few weeks, The nurses in the place are not compassionate for there duties,i only met 2 nurses that really wants to be there, the doctor not completely understanding his situation discharged him still very ill. The basic need is to ensure the person can eat an drink on his own and can understand you clearly,for a doctor to check for understanding is important,Doctor didn't take in consideration the man has illusinate. But im a bit to immotional at this stage however,they discharged him based on they need beds for other patients. He was discharge unwell and extremely sick,he was put into self care,how do you send a man that could walk now not walk out. I will complete my complaint as detailed as possible shortly.I want a assurance manager to discuss the way forward.When i called an asked for ma assurance manager i was advised we don't have one.How do you work in place an you don't even know your own process.When we returned with my brother at the hospital he was admitted with the name Mr no name no surname i had to go search in wards to look for him, when i asked the nurse she was watching a show on her phone and asked me to go ask the other one,she also was on her phone also watching a show.she asked me who said he was here,i said i had to call this hospital over 20 times for them to tell me his here,so i saw him in that same ward that they told me he was not in,but again i will give more detailed information on my complain
