civil case

I rented a storage unit it was being stored a their facility. I closed my account and was cleaning it out when the door started to fall and hit my son in the face. I rushed him to the hospital. My friend stayed and put my property behind the building. At 5:45 a.m. in the morning he received a call saying that they were going to put the stuff back in the unit and charge me til we cleaned it out. Then at 8:50 a.m. they called me saying we left a hell of a mess and to call them asap. So my friend called back at 9:36 a.m. and they said that they threw my property away. Don't they owe me for my property. And my sons hospital bill.
