So frustrating! I have no advice, unfortunately. I might have some idea of your frustration - a few years ago, I saw 2 dogs running around the icy/snowy neighborhood, recognized them and returned them home. As I turned to leave the home, I slipped on ice and literally flew in the air, landing on my right arm at the bottom of 12steps. Crushed my wrist and arm. I screamed for help, another neighbor came to my side, helped me, then looked at the steps. He made a comment about all of the ice on the steps.
I had no plans of suing the owner, it was an accicent and one can't always remove all traces of ice on their property. But I received a phone call from the homeowner's insurance agent a few days later, accusing me of all sorts of things, the 'helpful neighbor' claims to have seen no ice at all, and I felt I needed an attorney at that point to protect me and handle any conversations.
I ended up getting $1,000 from the homeowner's insurance, which made a teensy dent in the surgery, titanium wrist/arm, year-long therapy 3x/week.
So, maybe calling an attorney to see if there's anything you're missing or not thinking about will help? Good luck!
