Dementia patient has no one. No family, friends. No POA. He cannot pay bills, shop, do laundry, nothing. In own apt. Who can be in charge?

He lives in an apartment and doctors are trying to convince him he needs to go to a facility but he refuses. He has no family, no one to help him. He is so confused, unable to remember pretty much anything and is partially blind. I am CG with an agency. He buys stuff: has 3 walkers and a motorized chair for $200 that does NOT work at all. Never did. Looks like someone took a sledge hammer to it. People are clearly taking advantage of him. He cannot keep his apartment clean and just fired his housekeeper telling her that he now has someone that can do it... me. But... no... that is not possible. He keeps me running to the stores getting him groceries, clothes, shoes, prescriptions, etc. and I only am there 6 hours a week. She used to do the laundry and now I try to get that done with everything else he wants me to do for him. I helped him pay some of his bills but who knows what bills need to be paid and when? He does not. He needs to get to his appts. but he does not know when they are! He did not know who his primary doc was! I called the VA and found out, called that office and found out he has appt. in October. He did not know. But what OTHER things are NOT getting done that we don't know about? When a vet has no one who is POA... who can then act as one to help this man? I cannot do everything that he needs done. Thank YOU.
