BR Plumbing & Gasfitting LTD

I recently had a shower base installed by br plumbing, it cracked within days of installation, before walls were even installed. Cost me $850. It took 3 weeks before they even came to look at it, then the owner told me it was my fault because I didnt level concrete, but they poured the concrete under the shower base.
I showed him the instructions for installation, and his answer was I wouldnt follow the directions. Even though they told me it was done and needed no more work. A couple weeks now have gone by and I was told the shower base was repaired, base is still cracked inside and out. Looks like they just glued and spray painted it. The owner Brett told me he would refund my money, I would be happy with that. But he refunded me $240, not even enough to cover the cost of my damaged shower base. Now I need to get the shower base repaired or replaced, and hire another plumbing company to finish the incomplete plumbing and concrete. I am now farther behind than when I hired them in December. I would definitely not recommend this company.
