Unable to access App Store on iPhone

Hello,

If a message says 'Your Media & Purchases account has been disabled' - Apple Support or "You cannot login because your account has been locked”, this is not something anybody on this forum can resolve for you. You might be able to request reactivation by tapping Continue right from the alert. If that does not work, Apple provides a link with three options for this specific issue. Tap or click here and choose the self help method, or a contact option ➞ https://getsupport.apple.com/?caller=kbase&PGF=PGF63005&category_id=SC0245&symptom_id=23362 .

or for additional telephone contacts refer to: Contact Apple for support and service - Apple Support
