Has anyone else had a bad experience with an agency after they have reported concern for their elderly parent?

I posted a question on AgingCare about continual inappropriate and suspicious behavior of the maintenance man towards my Mother. She admitted that he was visiting her. She was having nightmares and fears about a man hiding in her closet. I complained to management. Nothing was resolved. He continued to seek her out. After I came in to Mothers apartment and found her with lipstick smeared all over her face I called the State Agency numbers sent in to AgingCare by email responding to my call for help in what to do. The Rape Crises Center sent an investigator out to see Mother and to talk to me. I was impressed at the quick reaction. However it was very unpleasant. The investigator proposed an inquiery by the Facilities Administrators with my Mother, and myself present. I was a volunteer at a Rape Crises Center many years ago. What would have been appropriate then was an interview with my Mom very discretely and in a sensitive manner. If getting Mother to trust the interviewer would take some time, the interviewer would recommend counseling. I was very disappointed in the present approach especially after having been a victim of management tearing me apart in former "Care" meetings. They were not loving meetings and the results were disasterous for Mother's health and well being. I said No, I did not want Mother being exposed to an interrogation. We subsequently got Mother out of that facility. That as over a month ago. She is in a very nice Assisted living program at another facility. What happened at the old facility still haunts me. Has anyone had a bad experience when complaining about a facility to management. Is it the political culture that has warped the Agencies set up to protect the resident? Is it that the residents in Personal Care who are elderly are not given the protections that a younger person would be given because of their age? This is just one of several matters that involved reports sent to agencies where there was no adequate resolve.
