Why do HHA's think it's ok to snoop through all areas of the house?

They snoop through every closet, drawer, storage. They eat and steal whatever they want. We used three different agency's in the Minneapolis area Legacy, Senior Home Care, and Carters Care .HHA's from all three thought our home was a free for all, snooping and stealing from closets, drawers,and storage areas all through the house, Eating our groceries and generally being disrespectful by refusing to take off shoes and eating in the living room leaving food messes on the coffee table and floor. M__va from Legacy even watched Pay Per View movies and blamed my dying family member. She was completely incapable of providing safe transfers for my loved one because of her recent knee surgery, she kept dropping him down on the toilet. She emptied the urinal in the bathroom sink, spilled urine on the floor while emptying the cath bag and just dried it up she wouldn't even clean it up properly my family member even had to tell her to wash her hands afterward. She would fall asleep on the job and when my family member would make noises to wake her she would tell him that he didn't have to be smart about it. Even though we complained to the agency they sent her back because they were apparently short staffed. There was no follow up call to see if things were better in fact things got worse as she seemed to be vindictively getting even for the complaint by scratching my dinning room table. Some of the scratches were deep and through the veneer. There was one room in the house that was locked and the woodwork 2 inches above and below the striker plate is completely gouged away. L___beth from Senior Health Care also had trouble emptying the cath bag without spilling on the floor and also refused to clean it up properly she also left the locking closure on the cath bag open several times causing the urine to pool on the bedroom carpet and dribble on the hardwood floors before I realized it was open. I had another hha from Senior Health Care J__et that was sound asleep when I got home. It took her several minutes to wake up even though the security system beeps twice when the door opens and the dogs bark. My loved one has recently passed away. He fought against having strangers coming into our home now I understand why. My experience has convinced me to never have in home health care again. The thefts so far as I can see so far were petty thefts which is why they think they can get away with it. Besides the groceries that they all ate, canned goods were stolen, pie pans, vegetable spray, Tupperware serving tray, lead glass salt & pepper shakers, Tylenol, cough drops, hardcover books, paperback books, a variety of other items that were stored in the bookcase, miniature decorative plate. two baskets were taken from a wall arrangement on my dinning room wall as well as a wall plaque from an arrangement on an upper level bedroom wall.
The one person I will never forgive is E. Carter for not telling me what she already knew which was that my loved one would not make it through the day. I told her for two days I wanted to be with him when he passed. She asked me for his razor before I left for work on valentines day he passed away about two hours later. She told me later that day as we waited for his body to body to be picked up that she likes to shave her clients, comb their hair and clean their nails before they go to the morgue. She always came to the house with two large bags but when she left on valentines day she was having a hard time getting herself and the two bags out the door at the same time. I have suspicions as to why. I don't believe that there is any justifiable excuse for my not being able to have that last moment with my loved one.
