Faulty New Wooden Floor

Recently paid for a new solid oak floor to be laid which looks great - however to corners of the lounge the floor has come away from the adhesive (laid on a concrete floor) and moves very noticeably when walked on
By the door entrance and hearth on fire it is pushing up where it has expanded to much
The floor specialist scabbled to original floor, leveling compound on it, dpm and adhesive
His advice is that the floor has taken so much moisture from the original concrete floor under the ceramic tiles in the hallway - the new floor is absorbing all the moisture which has caused the massive expansion - which has broken the adhesive under neath which has caused the DPM to be faulty.
how do we get over this situation where we have a useless wooden floor that has been paid for
