"After care is a disgrace."

My elderly father had a hip replacement and was sent home against his will the day after. He lives alone and has no family nearby. As soon as I knew he was being sent home, I telephoned the hospital to express my concerns but was simply told by the person I eventually got to speak too, that they only deal with private patient appointments and could only give me a number to ring. I rang the number to be greeted by an answer machine which I left a message for someone to telephone me urgently. That was three days ago and still no phone call..... He was being discharged within half an hour and as I live two hours away, my hands were tied and my only hope was that somebody would actually have the decency to return my call.
