you say there is noughting wrong with the steering even though the steering wheel is not center anymore and as soon as i let it go it goes at a 30 degree angle.I have been following this tread. If they already checked for alignment twice, then nothing is wrong with the steering, but it may be with suspension or brakes, after all it was a BUMP. I would check height in all four corners. Distance from center of wheel to fender, from bumper to ground. I am pretty sure one front corner is lower.
