hmmmm.....how about wood filling the hole and drilling a new one ? Call the company who did your cabinets and see if they can send a 'touch up paint/stain' of your finish for covering the wood fill? or better yet, they might be able to suggest the best way to move the knobs..??

do it yourself. make a template with cardboard and use a door where you like the knob position as your guide.

as long as the knob will cover the extra hole, it's an easy fix.

.....assuming you own a drill, of course.

Sorry about that. The fix suggested is probably very doable. If there's any problem, though, another route might be decorative knob backplates, depending on the look you're was going for. Some are extremely attractive.

One of the guys who came to do my cabs on install day did not have his "head in the game" (so to speak). Several of my handles were installed in the wrong place (not centered on the drawer). I was more than annoyed, but they came back out and fixed the problem. They were able to take the drawer fronts back to the shop and completely fix the holes. I cannot see any evidence of their mistakes even with my very discerning eye!
So you may want to hold the contractor responsible for his mistake.
Hope you get it fixed- that situation would bother me too!

Be sure it's the knobs and not the doors themselves that aren't aligned before you begin. Door adjustments are easy with the right hinges. Knobs aren't that hard with painted cabinets either.

Thanks you guys! Your responses are encouraging.

Yes, the doors are misaligned in many cases. I'm trying to find out how to adjust these "European" hinges.

That's my first step. I've already requested touch up paint, so I'll try to drill new holes. edlakin, your template idea is awesome!

Knob backplates another great backup plan.

I already have a very loooong to do list for my contractor and he is very sloooow in responding. I'm tired of waiting, which I'm sure is part of his plan.
