Poor FNB Premier Banker service - Uploading of documents

My premier FNB premier banker advised me to email my documents to ***. After emailing through the documents I got a message saying: " Dear Client, Please note that this mailbox is no longer available for servicing queries. By using the FNB App you can bank safely and securely from the comfort of your home. It’s super easy. Simply follow these steps: 1. First download the FNB Banking App from your App Store. 2. Then launch the FNB Banking App, and click on “Setup my Banking App” 3. Follow the simple instructions from there. This is of no help.

When trying to upload documents on the Personal Details section on the website I get the message saying: Compliance Status": Compliant, but you are unable to upload documents.

How then can I upload documents as suggested by the banker?

Poor service again by FNB!!
