[Fl] Baker Acted wrongfully and taken to hospital against my will. Hospital is charging me $1500. What can I do about this?

I was wrongfully baker acted under wrong pretenses and taken to a local hospital’s behavioral wing. The reason listed in the report was something that never happened. I was released within hours. They charged me over $4000, insurance covered most of it but I’m left with $1500. I feel it’s wrong to be charged for this entire situation. The hospital won’t reduce or remove the charge. What could I actually do about any of this?
