Indie horror film: 4 days, $200/day, genuinely unsafe stunts

Took a low-budget indie horror gig. The rate was $200/day for 4 days. On day 2, they wanted me to fall down a flight of stairs. No stunt coordinator. No pads. The director said 'just tuck and roll.' I refused and they were visibly annoyed but let me do a simulated version. On day 3, another actor actually got hurt doing a 'simple' scene involving fake glass that turned out to have real sharp edges. Nobody had insurance. I finished the shoot but reported them after.
