DMT Concrete Service

I hired Doug's company to come out and repair my back landing. The first time he came out it was still chipped and cracked in some places. I called Doug to let him know and he came back out, a month later, and it looks worse than when he even started. I then called Doug again and he kept telling me that he would come out and he never did. I finally just asked for my money back and he said he didn't have it to give back to me. I then asked if he could just give the money back in installments and he agreed to this, but I have yet to receive any of my money back and it's been over two months. I would highly suggest not using this company!
