Laminate Floor wobbles a lot when walking over a section of it

Hi, I’ve just recently had some expensive laminate flooring laid downstairs and have noticed that a large section of it bounces / wobbles a lot near where the old hallway was (we had the wall removed to enlarge the space). On closer inspection, it looks like the high point of the floor is in the centre of the room and everything slopes down toward the wall / old hallway area where this is happening. Can anyone tell me if the whole flooring has to be replaced with the floor levelled off? Or, can the builders just do say half of the room i.e where it’s most uneven. The laminate was laid on top of ply boards and the floor wasn’t concreted so it’s definitely not level. There is some underlay I think, I don't know the make of it, its thin and green in colour. What would you as the experts advise? I'd appreciate any advice / help. Thanks...
