im no tile expert but that seems like way to many issue not to complain.

Oh vay! This is why you check references! I've done my own tiling and even my first attempt was better than this botch-up. Tell me you haven't paid them! It's seriously horrific. Grouting will improve the look marginally. But whoever did this needs to be run out of town.

HI -- Sloppy job ! It's marble and marble is expensive and it should be installed perfectly . This is not !
