Worst bank when it comes to service and efficiencies

It is mind boggling that banks still operate in such antiquated ways, new app and web functionality but still the same bad service and processes at the back end, not to mention staff that cannot even read statements, then after i told them which line to look at o the statement they tell me the process will take up to 72 hours, after 72 hours passed already, it close to a week. Oh and it had been escalated twice on my request but NO feedback NO calls just NOTING, till i call again to explain the whole process again and just no joy! I deal with many banks and African Bank is by far the worst. If someone at AFB read this, forget about the digital front end's and applications and FIX your backend and your culture because without that you can make-up it as much as you want but wont make any progress. Build a digital culture and employ the right people, fox your back end processes, build in efficiencies and work on your digital culture!
