My concern is that all of your careful patching and scratching will only last a short time before new cracks will form or those repairs fail. You've patched a LOT of cracks. That should tell you something about the fundamental structural integrity of the entire pour. I would appear that either they didn't use enough steel in the structure, the prep-work for the base below the pour wasn't properly completed, or the PSI strength of the concrete wasn't up to snuff, or perhaps all three.
