The correct way to fix this is to build up the journals, and turn them back down, OR have a custom set of mains made.
I would be a bit concerned with .040 off the mains that the case hardening would be thin or gone. Additionally, shims will have to be made with the tab to fit into the slot so the bearings don't spin.
At the end of the day, I would NOT pay them unless they made it right. I have been rebuilding all sorts of engines for 35+ years. Any machine shop I have worked with mic's the journals BEFORE they start, and then asks me how far I want to go. There are all sorts of ways to resurrect a crank with undersize journals, however, none are cheap to do it correctly.
In a few cases where a mistake was made, I found that splitting the cost of "making it right" often times was the path of least resistance if the shop won't step up and make it right. You have to put a price on your aggravation and time. At some point, you need to cut your losses.
I probably would get a new crank in this case and have them swap out the undersize bearings for standards and call it a day........then never do business with them again. The quality of a business is not that they don't make mistakes........the quality of a business is what they do WHEN they make mistakes.................because crap does happen.

It is also very apparent that these folks are getting a lot of very poor and often very dangerous advice fro
