OP, yes, Apple does ask for proof of EDU purchases. It sounds like you did not know how to use Safari or understood that a $5,000 purchase in the EDU store may have required proof of EDU status.
Apple has price matched up to 10% in store (I always have that info ready on my phone) too. The same discount as EDU.
Apple -as many have said- do not read these forums.
I have had bad experiences with iPads too, and took a wash of $1,000 on the 2017 iPad Pro due to touch irresponsiveness which has yet to be addressed, it’s frustrating. Yes, the bending iPad Pros are ridiculous too.
I love the Apple pencil though and keep trying new iPads because of the pencil. Made some mistakes too like buying a 2020 iPad Pro for work that wasn’t compatible with my job software, and did not know this until after the return window. So I took a wash there too, but that was completely on me.
And with that mistake, I let go of trying to leave Apple or being angry at them because I have just as many issues with PCs (including my ignorance). If I eventually get a PC too, terrific. Doesn’t matter. I am aware that it can be as much me as it is the technology.
You found a solution with Samsung now, great. Enjoy it.
