Poor systems thumbs down to Discovery bank

I recently joined Discovery bank, moved my salary onto the bank and had my card delivered. after payday i struggled to make payment to service providers and withdraw money using my card because I'm unable to finalize the app transactions using their face recognition security application. I called the call center which indicated there is nothing they could assist with. What is mind blowing is that their is no other system they have in place or alternative should a client be in a position of not being able to conduct the selfie. They have no branches for manual assistance nor do they have an alternative system in place to ensure I do not find myself having being stranded, having finances but unable to access them due to the institutions lack of systems.
