Might want to take a quick video of you actually squeezing water out of the core of the board before contacting NS. Maybe go to a shop that carries NS and have them confirm it. Because if you contact them and just show them that pic, they're all going to have a nice laugh at your expense.
I find your story pretty hard to believe and they likely will too. Hence the need for video and/or shop confirmation.
