Damp under vinyl laid on quarry tiles

Hi. I'm totally at a loss of what to do or who to speak to. I had an extension built onto a semi-detached 1930s house and walls knocked through to create large open plan kitchen-diner with a mix of floor types... the original kitchen was quarry tiled laid on soil / ash, the original adjoining room which they knocked through to is plywood flooring laid on timber foundations with a cavity and the new extension was built jan-apr 2017 with solid concrete floor. So the whole room has 3 types of floor. I had vinyl flooring laid across all with a self-levelling compound underneath. The Vinyl flooring started to bubble after a year or so in the old kitchen area. Neighbour came round and pulled it up and found to be wet to the touch so thought there might be a leak from pipes installed by the builder's when they did the extension. Called the builders to investigate who also thought a possible leak.. so they dug hole through quarry tiles (without discussing with me I might add) and checked other parts but nothing found. The builder's then filled the floor in with soil then left leaving a 2ft x 2ft soil-filled hole in the middle of the quarry tiled flooring. Note that the builder didn't know the cause of the damp but suspected a leak from underground pipes from the kitchen island to the mains but ruled it out as an issue after investigating. How do I restore my floor? Don't know what to do or who to ask. Can you help?
