parked car accident

can anyone help. My parked car was hit and pushed up on the sidewalk. The car that hit it broke an axle. There was not much physical damage to my car, but the steering was messed up. Ins co authorized a wheel alignment, when they were to do it they said they could not because the suspensions were bad. They said this was a pre -existing condition..We ahd no problems with the car before the accident. My mechanic said he drove the car and did not feel anything bad in the suspensions. If they were bad would we have felt it.. don't know what to do?
