We really need to see the video. Please make it public!
There are 3 possible things that make an axis go the wrong way.
1) Either a limit switch is stuck,
2) the DIR signal is stuck, or
3) the stepper motor connector is wired backwards.
#3 seems unlikely because that would have been caught at the factory. #1 is most likely but you say you tested it.
X *and* Y axis not homing? This is very strange. How could both break during shipping at the same time?
Need to see the video.
