purchased music on itunes not showing up in downloads nor library what is wrong?

Hi i this isn't my first time purchasing music in itunes and it worked out fine the first time.

My brother gave me a bank gift card with $30 on it, and i entered the numbers to use for itunes, when i went to go purchase some music, my transaction told me that i bought the music, but it is not showing up in my downloads nor purchase history. Help please!!! 🙂
