It is entirely possible the school didn't communicate well, but be aware it's typical for a parent with a grievance to report not having received messages that have been presented to them several times via several different channels. And that's not even considering the ones who'll simply lie (every teacher will run into some of these), but just the ones who don't read anything or respond to phone calls.

Sure, but it's also typical for school admin to lie about the same thing happening when it did not.

I mean, yeah, that's fair. School admin is one of those things you had some thoughts about as a kid, and later learn you weren't only entirely right about them, but it's much worse than you thought, rather than one of those things where you realize you were wrong when you grow up.

I will never understand that logic where people try hard to avoid blaming parents

parents are normal people too, they sometimes suck too, just move on.
