Edge Landscaping and Maintenance

We used Edge to replace our driveway with concrete. At the time, it looked great. 6 months after, we noticed a lot of pitting in the concrete and pieces of concrete flaking off all over the driveway. It continued to get worse. I contacted the owner, he agreed that this was not right and shouldn't be happening. Since then, I was faced with all kinds of excuses, this went on for months with no solution. Since then, he stopped taking my calls and has wiped his hands clean. Very disappointed.
