Laminate Flooring Shifting
Sounds like the laminate wasn't 'climatized' for a week prior install or some of the locking tabs may have been broken during the installation. That could have happened as a result of 'hammering' the boards together rather than 'clicking' them together and then gently tapping them.
If the shifting parts are every 5 or so rows you may be able to take up the floor up to the shifting joints, run a line of wood glue in the joint, wipe excess glue off and tape the top of the joint with masking tape to hold it together until it dries.
