Billing in AppStore

Hi, I’m being a billed every fortnight for use of the AppStore and apple music when it’s supposed to be monthly and now as I don’t have money in my account until tonight, it won’t let me use a FREE app because apparently it has to be updated which I can’t do until I pay for my account.

I’m really unhappy about this and I would like it fixed as soon as possible because it just simply isn’t fair and I’m honestly ready to cancel my account and go to Samsung.
