To the OP, I'm sure you knew before 9/4 your kid wasn't skating over the summer so what is the point in bringing it up now? If the agreement you signed back in April didn't spell out a preseason camp, etc., why did you sign it if you thought it so important? If you thought coach run practices were important in the summer, why didn't you ask the coach about it when he begged for your child to join his team? Hopefully you are getting my point. Now if you were promised all these things and didn't get them that's a different story but assuming you weren't, it's really on you.
Do your due diligence before you commit next time so that your expectations are aligned with the coaches/organizations realities. The best part of our current hockey landscape is their are lots of choices available to us parents that should allow us to find the right fit for our future GOAT's.
Sorry your kid didn't get any summer ice time
