? Help w/ accident where floor of elevator failed to level due to power Co phase failure. i was labeled a liar by emp-tech.said this was not possibl

I was carrying supplies so did not see over them to realize that the elevator floor had not come level with permanent level of the hallway floor I stepped from. Because of not expecting it, I hit hard with my left foot, jarring my foot, leg, and back severely, Damage to lower left leg occurred, which has healed. My lower back was harmed, still causing difficulty to this day. I was only told specifically Sunday, Oct. 23, 2016 that the cause of this occurring twice with a couple of month gap between the incidents, and a third time when I was trapped in that same elevator when the door jammed that the cause was a PpL(electric power company) power phase malfunction that stopped the elevator at the moment of the malfunction, these phase malfunctions also damaged the large A/C unit on the roof of the church I cleaned as my moonlighting extra. I have physical, employment, educational goals, and future plans injury that has and is bringing serious difficulty.
