Standard bank poor service

i have just spoken to a consultant today and they cannot give me details on my account. They cannot calculate what the compound interest will be on a 2 year fixed deposit . When i asked questions they told me to wait to see the manger after already waiting for an 1hr just to see a consultant. The app they recommend for banking is not practical when compared to other banks like ( Capitec, Nedbank ). The app does not give important information to the user it cannot tell me when my investments mature this is a basic function ( start of investment , maturity of investment )
