I received a full load of topsoil that was either a bad batch from their supplier, or they had a bunch of rocks left in their truck from a previous load. It was not usable. Spoke with the owner and they sent a crew to come out and remove the rocky soil with a bobcat. They came back and gave me a new truck load and the soil is perfect, and free of debris.
Mistakes happen, and like previously stated, I'm not sure if it was their mistake, or simply a bad batch from their supplier, but they corrected the issue completely.
Delivery driver was a good guy as well.
