Worst paving company I have ever worked with

Worst paving company I have ever worked with. Do NOT use them for any large project. Excellent salesman but that is where it ends. After starting a week late, even before delivering any materials, they already insisted on the first progress payment which I foolishly did. What I expected to take 2 months turned into 6 months of false promises, very bad workmanship and double charging for items already included in the original quote. If you don't watch them like a hawk they will use the wrong material, (sand with a few rocks instead of real G5) omit using cement on the stabilisation of the base, (because the cement wasn't delivered in time they simply omit it) don't mix the sand and cement before grouting, decide they don't have to use water to wash in the grouting even though the salesman promised proper wet grouting. They don't compact properly as explicitly promised by the salesman.
