"Guideline 3.2.1 – Business – Other Business Model Issues – Acceptable
The seller and company names associated with your app do not reflect the financial institute name in the app or its metadata, as required by Guideline 3.2.1(viii) of the App Store Review Guidelines.
Your app must be published under a seller name and company name that reflects the financial institution name. If you have developed this app on behalf of a client, please advise your client to add you to the development team of their Apple Developer account.
Please note that submitting documentation showing permission to publish this app on behalf of the financial institution will not resolve this issue. This app must be submitted under the financial institution’s own Apple Developer account.
Once created, you cannot change your seller name or company name in iTunes Connect. For assistance with changing your company name or seller name, you will need to contact iTunes Connect through the Contact Uspage. Select Getting Started from the first dropdown menu, then select General iTunes Connect Inquiry to contact the appropriate iTunes Connect team."
