Unbelievable! This is obviously fixable. I would not be surprised if a brand new rim is out of vertical true by 1 or 2 mm. The vertical wobble can be fixed very easily by tightening the spokes under the high spot.
(BTW, check that the bump isn't due to the tire: sometimes a tire isn't all the way seated, and so there appears to be an out of true rim but it's really just the bead of the tire.)
