"No discharge planning"

My 74 year old mother was discharged 3 days post ORIF surgery to tibia.   She lives alone in a 3 strorey house with only a kitchen and small bedroom on ground floor- no toilet. She was unable to carry out personal care  or prepare food/drinks independently. I (daughter) have to take unpaid leave to look after her. I was never consulted about her discharge.   I am unable to be a full time carer due to own young family and work.   We had to buy a second hand commode and mobility aids.   We have no appointment time for follow up clinic and no advice on leg brace- mum has a pressure sore from leg brace developed. Extremely let down, and I also believe that the service was in breach of the Carers Act.
