Best Patio/Porch Construction in Orlando FL

Work on our new patio has not been completed, and not only has it not been completed, I was told by an A+ rated contractor through the BBB that the patio must be demolished and redone completely in order to structurally hold a swim spa.  It was poured in different stages with different concrete causing instability in the seams, different colors and texture.  The pour is NOT thick enough to support a 15' swim spa.  It rained when the concrete was wet and did not have plastic on it causing pits with exposed stone, puddling, etc.  It also splashed up on our screened in lanai, I had to pick off the screen itself and I cannot get to come off of the aluminum kick plate.  They've left the wood form up on half of the patio, left rebar and cement chunks in the yard.  We've left multiple messages, phone calls, emails...No response.  I just checked the license number they put on their quote today and it doesn't come up on myflordalicense.com, so I'm not even sure if they 're legitimate.
