Hi there, bones1974.
I see that you're unable to purchase applications in the App Store. You receive a message that your Apple ID hasn't been used in the store and asks you to review your account. Then you're immediately sent back to the sign in screen again, and I'm glad to help.
Change, add, or remove Apple ID payment methods -- Make sure your Apple ID has a payment method available.
Payment methods that you can use with your Apple ID -- This article provides the information regarding the payment methods you can use. Be sure to review country- or region-specific information under "Payment methods by country or region".
If this doesn't correct the problem, please describe the issue in greater detail. Please include the full text of any messages you receive. Also include which device you're using and which operating system it's on. The more information you provide, the better we'll be able to offer additional guidance.
Take care.
