Oh dear, another cowboy builder website. They normally have to pay to advertise on their, so the website owners tend to support them rather than you, but it's still worth putting in a complaint. Otherwise, threaten to resort to social media to put the story online.
I thought the wood was too dark for oak, but a lot of the blocks had the right grain for it, so I didn't consider it to be walnut, but that should be fine with ordinary screws, however, you still need to check that they have slotted angle brackets, not fixed ones.
So have you paid them all the money yet. If you work out the sizes of the worktops, you may be able to move them round, and not have to replace them all.
Be prepared for a battle, but just stand your ground, and outglare them.
