Hey Annexedwa! If you've built your app in flutter, you have to Add Localized Languages in the info.plist and in the xCode side to show these languages on app store.

If you haven’t faced any rejection due to spam or serious guideline violations, then it’s better to cancel the current submission and resubmit it — sometimes this can help resolve the issue.

It means there are already many apps on the App Store with similar features and ideas. So, they are asking you to create and upload an app that includes something new, innovative, or different — something that makes your app stand out and gives users a reason to choose it over existing apps instead of just copying what’s already available.

Ready for Distribution Status means that your app is already released/live on app store. You can confirm it by searching your store name on app store.

There is 0.009% chance to get back your developer account , and about your payment it will be processed within 5-6 months , so Don't remove any your business details from your account till you receive that payments.

This is happening a lot these days. Apple is taking longer than usual to approve Developer accounts, even when everything is submitted correctly. I recommend sending a short follow-up email to (itunesconnect @ apple.com) with your Apple ID and mention that your enrolment has been pending for over a week. There’s usually no missing step—Apple is just doing extra verification.
