Rear End Collision Advice

Hello! My fiancé and I were rear ended by an infinity suv this past weekend leaving San Antonio to go back home in Austin









They hit us pretty hard on the left side leaving some pretty significant damage to the entire left back corner of our raptor. The bumper metal frame is bent on the left side. Left side bed panel is crushed into the fender flare (which is toasted). Bumper ripped off. I believe there is a problem with the left side axel as well just base on how much higher the left side frame is bent, not and expert just going off visuals. Was wondering is anyone had experience with this kind of wreck. Also, cherry on top, they other driver was not ensured. They in fact did not have drivers licenses either.
