Can’t access App Store or iTunes

My phone crashed, jacked hacked or other while doing backup. Tech told me to backup and erase.

Now phone requires me to use Apple ID to access App Store or iTunes to replace apps on my iPhone 6s. However.

When I enter either of the above, I get stuck in a loop: “This Apple ID has not been used in the iTunes Store. Tap review to sign in,” and signing in brings up the ‘tap review’ direction ad nauseaum or however it’s spelled. HELP
