They put the doorhandles in the wrong place on most of our drawers. We complained and they had to replace the whole front of all the drawers that were wrong.
If it bugs you (which it will cause you have noticed it), then tell them asap and say you want them fixed. If they can level the doorhandles by drilling new screw holes and the new handle position covers the old screw holes, then that would be ok, as long as the handles aren't loose as a result. If not then they should replace them. If they do fix them (you should be able to tell by looking at the screw patch up job on the inside of the drawer) then make sure you yank them and pull them with a reasonable force (like kids would) to make sure they will be ok after handover and don't come loose.
