African Bank False “incorrect credentials” Error Message

I recently visited an African Bank branch to have my password changed after being blocked from using the app (incorrect credentials). This, even though I’d been using the same password. And now, two days later, I’m getting the same error message when trying to log into my account.

I’ve been to their branch for the same problem twice already. Both times consultants advice that it’s because I’d entered incorrect credentials. Which is not the case, as I’ve been using the same password (it’s in fact saved into my phones password storage).

Is it a technical error on their hand? How do I permanently fix this because I’m unable to do transfers, let alone have any control of my money. What’s worse is that this can ONLY be fixed at their branches.
