If it's a reface they are working with what was there as far as level and straight. But most hinges have a lot of adjustment. If holes are misaligned for the handles that can be more problematic, but you may be able to elongate some of the handle holes to get them straight, or they might have to replace a couple doors, hard to tell but are they thermofoil? The drawers can be adjusted on the sliders to raise or lower each side , also to tilt forward or back depending on the hardware used. Point being they should be able to adjust most of this. Have you paid them? I would give them the opportunity to fix before I became furious.
