Engineered flooring problem gaps between joints urgent advice needed!

[Denisss]

Hi all! I have this floor which I have installed myself. The problem is that it has quite huge gaps between boards (it goes into slots but is not secured by a click system as most floors). Now I'm trying to get my money back and the path floor sellers are routing me through is to have full independent floor inspection which potentially could cost me about 420 pounds: ''The only possible way for you to have your flooring lifted up and replaced would be to have a full impartial independent inspection. The cost of this would be about £350 +vat (which would be refunded if the independent inspection showed a manufacturing fault).'' Manufacturers inspectors were at our house and found some installation mistakes, three end joints which should never be installed that closely, some uneven floor in some places. But they never addressed gaps problem. Is there any chance that independent inspector will rule in our favour please? Can these gaps be named as manufacturing fault?

I would really appreciate your advice guys!!!

Did you glue the joints?

Is it T&G

Was the wood acclimatised to the room before fitting?

Not fixed correctly.

Badly fitted but you may be able to lever the end of the run of boards to close up the gap

I don't understand why you didn't notice you were leaving those gaps while you were fitting the floor.
