Maybe the possibility of another contractor attempting something?
Stephen,
From the pictures it appear the areas are etched, the caused who know for sure. What’s interesting is the round appearance of the etching. This could be caused by the setting materials ,it could be efflorescent that making the stone appear etched.
The fix is going to be repolish the stone, if these are etch marks if polishing does not remove them then you may need to hone and polish. Prior to pricing this job do a test to see what you need to do to correct the problem.
If this stone is stone is not a polished finish and is more of a honed finish you could use a honing powders or the velosity pads from StoneCare Central
