Who can I call for assistance?

I’ve looked for help everywhere and cannot find anything on personal items being stolen when admitted to hospital. I had two rings on when I checked in and they removed my large silver ring but I was allowed to wear my wedding ring. They placed my cell phone and I thought my big ring in with my cell phone. I was in hospital for 6 days. When I was discharged, my ring was not in the envelope. There was a checkin page that marked all the items I had place in their care. I never seen this sheet until I was being discharged. I would have questioned why they only marked one ring and why they said I had shoes on (which I did not). I was not even shown this page because my signature is no where on there when it should have been signed in and out. It had two spots for patients signature as I stated one in and out and I signed either one. The same day of me departing, there was a woman in the van with us that had her sterling silver rose necklace taken as well. I’m not even sure if I am asking the right site. No one at the hospital will help me. Does anyone know what or who I can contact to report the hospital? I’ve already made the police report. If they would just look at the video it would definitely show me taking the ring off and giving it to the two nurses but they keep saying they would, then they say we can’t get the videos, so I’m lost on what to do next. Thank y’all in advance and I hope this question is allowed.
