Ultra-Loc Interlocking & Concrete

They did interlocking in my driveway,sidewalk and patio. they rushed the job to finish in 2 days. They did not do whatever was written in contract. They did not glue retaining walls properly and wall bricks are falling now. they did not compress driveway enough and it is sinking now. I have called Sean(Owner) so many times to fix these problems. but he is making excuses and did not show up to do repairs.He gave me two year warranty, but now just playing games, do not pick-up phones.I have very bad experience with this contractor and would not recommend any body to hire him.
