2019 Ram 1500 fuel system problems

I was driving a new truck i had purchased from a dodge dealer , i was rear-ended at highway speed, the truck lost control and went off road hitting a earthen burm head on, flipped and came to rest on the roof. The traction control didn't work, the front impact airbags did not deploy and the engine was still running while the truck was upside-down Download of the trucks ECM shows the srs seat position sensor was not configured from the factory.

For the past month my truck is unable to get more than 1/2 a gallon of gas when refueling. I brought it into the dealership and they looked the truck over and advised they couldn't find an issue. Told me to bring the truck to a gas station with a longer nozzle. I was also advised they would reach out to ram for another solution. No follow up still having issues at multiple locations, fuel also spills out of the tank when the nozzle stops working.
