App Store not letting me download free games or even let me update apps I already have!

Ok, so I tried purchasing a item in a game I have (not knowing how much I have in my bank account). App Store denied it so I'm like ok whatever I don't care. Well now whenever I try to download free apps or eve. Update apps I already have the store makes me sign in, and wants me to update my billing information because there was an error with my last purchase because it didn't go through. Ok why is it doing this? It didn't go through I don't care I just wanna update my apps and be able to download free Apps without having to update my information then apple charging for something I don't want anymore.... Can anyone tell me how to fix this? I already tried removing the card! I don't have a "none" option when I try to remove it so... Yeah
