If they were done with post haste, they should have been set up as not to move within an hour. My guess they weren't done well.
Get an old school car jack and get them out. Then get regular cement, line them up right, and once they are in place make sure you pack the cement down well to make sure it goes into all the crevaces. My guess is the post haste hit something on the way down, set up in a few minutes, and then left a big empty spot below.
