"My mother being moved without informing anyone"

My 92 year old mother had been in Fordham Ward recovering from a hip operation. When I came to visit her on Sunday 21 February I found her bed empty. The patient next door told me my mother had been moved to Clacton. I went and found the sister on duty and she said the nurses on duty should have informed me. I was down as the first contact. My mother was moved on Saturday afternoon, she herself did not know what was happening and when I eventually found her in Kate Grant Ward at Colchester she was upset and frightened, she didn't know where she was. this lack of communication is appalling - I was shocked to find her bed empty. I would like to know why I was not told that she had been moved.
