How do i get the tax ID# for MA training school? They did not mail me a 1098T form and i spoke to the secretary but she refused to give it to me, isn't this public info?

i paid in 2023 for a 6 month certificate program, i am halfway done with the class and they refuse to provide me with the tax id. She told me that because i did not use my fasfa loan i cannot claim this on my taxes, which is false information. please help.
