Luxury Vinyl Flooring nightmare

Hi all and happy new year! Looking for some advice please. We had luxury vinyl flooring (LVF) laid in our new kitchen extension by a flooring company here in the UK. They did not check moisture levels beforehand. It was covered with protective mats on their advice, which were not stuck but free. We subsequently had our kitchen installed. When the mats were removed all the LVF came up. Some of the tiles were now under the kitchen units and so have been left. The remainder are now stacked, covered in glue and look really bad. The flooring company is waiting for moisture levels to drop further but the tiles now look terrible and I’m worried the ones left will not be stuck properly. What would people advise please…? Should the tiles be ok to re-use and will the floor be even/flat if they’re re-laid? Will the tiles that are part-under the units be ok to leave even if they’re lifting too? New kitchen also covered in dust…!Many thanks…
