So this memory place has stopped my father from going with family. What is going on?

They stopped all outings to my house and stopped him from doing anything outside those 4 walls he looks at every single day. They stopped us from entering his room. How can we check to see if he needs anything. They have destroyed some of his clothes. No replacement. They have changed the visiting hours again. This is like the third time that has happened. His visitors have to have visits monitored. And the hours are Now 10-3. Everybody out when staff leaves. No visits on weekend at all!!! What is going on. Used to be able to stay until 7 and walk to his room. Can’t walk down the hallway now. Really memory care? Really, what do they think this does to the person living there? It’s horrible.
