What authentication?

How is it that African Bank has no email address for complaints from customers? It's no wonder why even the employees act so careless, thoughtless and without fear of the fact that customers are there to be served and for anyone to serve me while busy on personal calls about home stuff and for other employees to just sit on their workstations and just simply chat on their phones, this is because they know customers have to go through hello Peter and most of such complaints are never even responded to by this company. Such a disappointment especially because I recently opened an investment account and I'm only here for authentication as I need to register for online banking. Did I make a mistake and why am I now visiting a branch 2 months after opening an investment account? What authentication must be performed that want done the first I opened this account?
