Best Concrete in Tampa 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.

I need a contractor for several jobs. I gave this group of clowns a small job; to install a safety handrail in the pool. Seemed simple.
They sent one worker and 1 supervisor; a manager named Bobby. The manager did not much; mostly watched the poor guy work in the heat.
When they finished and it dried, it was very loose. I called them back, they said oh, yes, it is loose. So they re-did it. I let it set overnight (they said it would be good in 20 min). It was worse. Very unsafe. Very poor workmanship. I brought them back to show them (a 3rd time) and they offered to fix it, but I told them to go away. I believe in second changes, but if you can't figure it out in 2 tries; you probably won't. I asked for my money back. They said no. They do not stand by their work. They lie about their abilities and they do not get the job done. I suggest to avoid BMD. They created a serious safety problem with the rail and they do not have the ability to do the work....and what they did was sloppy.
YOU SAID YOU OFFERED TO FIX IT. Liar. Yes, you came out a second time and fixed it. It was worse. Why would I have you out a 3rd time? I asked for a full refund, but would accept a refund on the labor. Nothing from you, i had a real professional out to fix it. He said you used the wrong cement and did not even have a brace on one pole insert. He said whoever installed this did not know what they were doing. You caused a dangerous situation. You lie and are unprofessional and unskilled. To anyone: Use these amateurs at your own risk.
