FNB The worse bank - Terrible support unhelpful.

So I am trying to pay my staff via eWallet and like just about EVERY Friday FNB systems go offline. I am told its a nation wide failure and that FNB Staff must be going home and thats why its not being resolved. Two things how does a bank and I use that term very lightly with regards FNB not have redundant systems in place to prevent their system going offline. How do they not have IT staff to make sure their systems don't go offline and if they do resolve the issues.

HOW DO I PAY MY STAFF WITH A BANK THAT CLEARLY DOES NOT CARE ABOUT IT'S CLIENTS. I KEEP BEING TOLD "THERE IS NOTHING WE CAN DO"
