The same happened to me near our apartment complex, fell over a slab which was quickly repaired the next day, had to have steel pins put into my ankle. I approached the insurance company and was told I would have to pay my own way to sue them and they were insured for public liability for millions and I would lose the case. When I approached a company to deal with this for me in Tenerife, they said it would take probably 7 years before it went to court, I would probably be departed from this life by then, so that was the end result.
