Square boxes

Kitchen designers!.
You'd think they would know how to operate properly their CAD program and have some clue as to what to do.
Our new kitchen is not the usual square box shape, but kind of wedge shaped and this seems to confuse them and their computers.
This guy couldn't work out the angle so just guessed, ignored the boiler position because he couldn't make it fit, and left the worktops short on his finished 3D image("just imagine it goes all the way to the wall...ha ha).
Half the price of our first quote but half the kitchen missing.
I'll not be buying from the big orange shop i think!.
