Hello Nathem , I am very sorry for the bad experience you have. First of all, I need to clarify that, first, the cracking of the board is because the carpenter did not drill holes in the board before you asked him to repair it, which caused the board to be stretched apart by the screws. Second, because you asked the sample to use solid wood instead of MDF, in order to ensure its appearance, we can only use invisible nails that do not affect its visual effect for reinforcement. In general, we are deeply sorry for your situation, and as we communicated, we are willing to remake a sample and shoot a video for your confirmation. Thank you. Best regards, Jack
