do you have photos?

No, appliances can be adjusted for additional clearance.

I believe you mean the aide panels of the cabinets that hide the fridge not the fridge itself. Their options were to undercut there or have 1/4 round, I’m sure you prefer them being undercut so it disappears ( presuming it was nearly done)

Pics of the job they did BTW that flooring should have gone under all appliances since if not you will have a hard time removing the DW for sure.

Floating floors like vinyl requires an expansion gap at all walls and permanently installed furniture like built in bookcases and kitchen cabinets. It does not go under those items. It should be in all of the appliance alcoves though.

Not only did they butcher your cabinets for no reason, they built in future problems with the floor with an incorrect install. It should have been 1/4” shy of even touching the cabinets, and then have had 1/2”-3/4”shoe molding cover that gap.

Print out and read the instsllation instructions for your flooring. Highlight the relevant sections that were not followed. I’m sure that there were more than just the issue with the expansion gap. Grab your copy of your contractor’s License and insurance. You may need to file a complaint or a claim. Have all of that with you, and conspicuously visible, for the in home meeting that you request with the owner of the company.

You are owed repair of the cabinets, which may entail just using a bigger molding than shoe molding, or replacement, depending on the butchery. You are due the floor being relaid in compliance with the manufacturer’s requirements. Including any prep steps that are skipped.
