My mother has a Home Care worker thru Medicare that is supposed to come and help her clean and go shopping for her. However, my mother has told me that she comes and just sits and reads a magazine and leaves her with no food in the house. I have tried to complain to the agency but have gotten no results. What are my mother's rights?? She is getting the service thru Medicare and is not paying for it but she needs it because she is unable to shop for herself due to a recent fall.
