"B grade" boards delivered, instead of "A grade"

A few weeks ago, I wrote a review on this business (Boardmaster) about 2 complaints. The first had to do with their delivery people damaging my floor while placing the boards delivered. They pulled/pushed the said boards across the floor instead of gently placing them down, and management's refusal to come and investigate; and secondly the likleyhood that they had delivered "B grade" boards instead of Ä grade". I have pictures of chips on the boards after being cut by a professional board cutter that indicate that these were "B grade". I wish that I could append pictures of this. The board cutter confirms that these boards were "B grade" So, be very wary of Boardmasters.
