That is a bit shitty.. not quite sure of.a solution at this stage, other then to remove them and do it properly, are the tiles staggered pattern? You might be able to use slightly bigger spacer on the window rows to get The tiles closer. I have used this solution when tiles are slightly irregular sizing (esp glass). You'd be hard pressed to notice the difference in spacing.
If they are already fixed and your using white grouting I would just suck it and negotiate a discount for poor workmanship.
