Excavation Issues

We left for Bear Lake Friday with the understanding that the excavation would be done on Saturday. We got back tonight, and there is a hole in the ground, but it doesn't look like I expected it to. The perimeter is excavated, but there are still buttes in the middle of the garage and the middle of the house. I thought we agreed to remove everything from the whole footprint. I also see what looks like root fibers in a few places, which I don't think is allowed. I left a message for Jason.
