2014 Ford Escape seat belts problems

My car was stopped in traffic and some one hit it from back coming at a speed of approx. 35-40 miles/hour. Driver and front passengers hit their faces and knees on dashboard. Both seat belts (driver side and passenger side) did not restrain and stop passengers moving forward. We have noticed this problem on both seat belts (driver and passenger side) on this car (2014 ford escape se) since we have owned this car that both seat belts (driver and passenger side) are very lose and does not restrain when pulled…

The rear seat belt buckles are stuck underneath the seats. I was able to force one up by reaching my arm underneath but the plastic is bent up and the latch does not push in making it inoperable. It appears there is metal piece on the edge of the seat cushion that keeps the seat belt buckles from coming up to top side of seat where they would be accessible to passengers. I am not sure if this problem was like this when I purchased the vehicle or if it occurred when the seats were folded down at some point.
