Foundation Problem

The buyer of this home was worried about some cracking in the walls of the home he was getting ready to purchase. The buyer showed me a receipt provided to him by the seller from a foundation company that had performed $20,000 in foundation leveling and jacking in certain areas around the home.
Photo 1 is what I found in a dark corner far from the crawlspace entry. There was a hole that had been dug next to the footing under the foundation wall that had developed into a sink hole six foot wide and two foot deep. The hole also went two feet back under the footing. The other end of the sink hole that reached ground level was twelve feet away on the outer side of the foundation.
The second photo is of the actual repair which only consists of what appears to be a crushed block and other debris.
