FNB - how can we NOT help you?

I had to reset my username and password on my online banking and have followed the prompts and confirmed the change. However, when trying to login with the new details, the system told me that the details are incorrect. I used the chat function on my mobile app to require assistance. I was not helped. I was waiting for over an hour and got passed on to 5 people in that hour, none of whom could (or would) assist me. I still cannot access my online banking.
