I was assisted by the clerk, but when i tied to log in I could not and no matter how many times i tied my login attempts could not be view by FNB online assistant. So went to the bank to get assistance Change all my usernames and login details, but i still could not login. So the manager to get rid of me quickly help me get my app to log into my Business account. So when i try login my internet banking still nothing but my app runs on my new login. Yesterday I struggle with the phone assistant and he helps me now my internet banking but my app is blocked. The assistant keep telling me change my username and password to reset my app but it does not work. I get sent to the atm to activate my banking. But it does not work.

I had to change my username and password about 15 time Now I am Done. Done with going back and forwards to the bank and ATM done with paying to stay hold for hours at a time and with online and telephone assistant Hanging up on me , but i hold on for hours on end, and when cant or dont want to help they just end the call
