Best Way Stone Ltd

In June 2021, I had the contractor replacing my old interlocks with BWS. It looked okay at the beginning and I also blocked access to the driveway for almost 3 days before I parked my vehicles back on the driveway, but on the second day I started noticing that there are chips off on the stones, and some even have cracks. I took photos and asked the contractor checking on it and now I am still waiting for their reply telling me how they want to resolve this quality issue of their stones. The stones are supposed to be solid and should not be easily chipped. I hope that my case can be resolved soon. I only attached few photos but there are more.
