My microsoft account says that I have not bought Minecraft and I am wondering why I have to...

My entire childhood was Minecraft and I wanted to play some more for nostalgia but logging in has shown that I apparently do not own it. Not sure what is going on but I am frustrated. I am 100% positive it is the correct account and email address. I also have the email proving that I migrated it from my Mojang account. What do I do?

:)
