Something bad caused that and I wouldn't fire it any more. It needs to be returned unless it was an 'as is' deal. Whoever sold that is crooked. Anybody can see that's way off being right. If you can't return is the best you could probably do is a wall hanging or a paperweight, but since I'm a foolish person, I would ask if there is somebody that could straighten it. I don't know if the factory would be any help but they would be the best bet. Maybe they have a magician in house. Maybe they would replace the side? They might make you a deal on a new one or something. If it can't be put back in specs, ditch it.
"Magician' is a strange word to use, but believe me, I've met a few.
