No back up when system **cks out. Not acceptable

Here I am standing in checkers for now close to 40 minutes, because the Nedbank app is not working. Okay, no problem glitches often happen for various reasons, but how is it that such a well established business has no back up or contingencies when the system **cks out? I cannot even transfer the funds on their USSD or NetBank option and not even the call center. Which means on a Monday I'm stuck at a checkers an hour and a half away from home on my way home from a getaway because I cannot transfer funds into my account. But do the bank chargers change or get less every month, no! Nedbank this is completely unacceptable, I've been banking with you for more than 10 years I left before for Capitec because of exorbitant bank chargers, I think maybe it's time I give FNB a try.
