This app is not made by, run by, or connected to NCBA in any way. It's an independent tool for tracking your NCBA investments by reading the statements NCBA already sends you. If something's wrong with your actual investment or account, NCBA is who to contact - this app has no connection to them and no way to help with that.
Add the monthly statement NCBA emails you, and it keeps track of things for you:
Only you, signed in to your own account, can see your balances or transactions - see the FAQ (in the footer) for more on this.
Found a problem, or have an idea? Use Share feedback at the bottom of any page. That's the only support channel for the app itself - NCBA can't help with it, since it isn't theirs.
