Tile by Jason

I hired Tile by Jason to install long plank (8"x48") rectified porcelain tile in my home. I chose him because he had numerous reviews on Facebook that were all 5 stars and his price was better than anyone else. I was warned when I purchased the tile that the installer needed to know what they were doing and the floor needed to be flat or the tile would not look good. I met Jason at my home before the job was started so he could look at what was being installed beforehand. I emailed him the instructions given to me by the manufacturer prior to the start of the job. He assured me he could do the job. His bid was ~$3900 to install 1424 sq.ft. of tile. Two weeks later he showed up on time and on the appointed day to begin the install. He asked for $1000 to start the job and stupidly, I gave him the money. His crew started work immediately. We hadn't moved into the house so I gave him my key so they could have access. By Friday, they had installed half of the tile and he asked for another draw of $2000. I asked to meet him at the house to pay him and if he had the key so I could see the work, which to date I had not seen. He told me he didn't have the key so we just looked through the window at what was done, and it looked good to me. Stupidly, I gave him the requested $2000. Over the weekend, I returned with my wife who had another key and went to look at the work closely. I found significant lippage in many places across the floor. The lippage found was over twice the allowable and a quite few places would have cut someone walking barefoot across the floor. There were also tiles that were chipped installed on the floor. I met Jason at the house the following Monday morning and showed him what was wrong. There were so many places that were bad that the floor needed to come up and be redone. He told me that it's tile and it wouldn't be perfect. He told me if I would let him finish the floor and grout it in that it would look good. He then said he'd give me a couple of days to think about it, he then packed his tools and left. I had several tile people come out and look at the job afterwards and they all concluded it was bad and some spots were dangerous (cut hazard). I have since found out he did not use thin set for large format tile as he should have, he did not get the entire floor flat as he should have, and he did not use a leveling system as indicated in the installation instructions I gave him. I have since had the fllor taken up by a reputable company. most of the tile came right up and I was able to salvage about 75% of what was put down. They ground the floor, used a self leveling system throughout the house, they are using the proper thin set and a leveling system as indicated by the manufacturer. I am out the thin set material, the tile that's been cut, chipped or broken coming up and the money I paid him. I also had to extend my lease on my rent house another month because of the delay to fix the bad install. In total, I'm out about $6,500.00.
