Loc Tite Interlocking

I hired this company 5 years ago. The salesman person named Foti was a charlatan. He changed the quotes several tomes and after the contract was done, disappeared. The owner and chief named Greg cut the edge of the work and installed low quality stones. He was the one man show with unprofessional teenagers on the site.
After a few months all stones moved around and the gaps appear and the driveway and backyard appeared bumpy. Non of my neighbour’s driveways look like mine done by the other companies. I tried to contact the manager (Greg) every year during pat years, no avail. I decided to take them to the court.
