Re-Lock Interlocking Stone

This is the second time I have used Re-lock. This first time was for driveway interlock refresh and that was fine. This time they refreshed about 500 sq. ft. of interlock which was done well but the garden wall they built was the wrong colour brick and they followed the grade of the land instead of level. One end of the wall is about 8" higher than the other and looks like crap from the street. I offered to pay for the brick (to get the correct colour) and about half the labour to rebuild it properly. Never heard back from them again. Needless to say they wont be used for the remaining 1000 sq. ft. of patio next year.
