horrible website

This website has nothing to do with gift cards. You also cannot log in to download music. It seems you have a serious misunderstanding of how all of this works. Downloading music is done through iTunes, which is a separate program, and not an internet browser. You also check the balance of your iTunes credit from there as well. If you want some help, someone should be able to assist you, however if you wish to be done with Apple, then why did you come here to start with, since Apple does not participate here in the forum.
