Capitec Bank at its worst again

The so called technical glitch where the Capitec Bank app didn't show the correct available balance on the 25th really costed me. I had to login to online banking to transfer money to my wife. I made a mistake of transferring to an old FNB account. Now I'm asking Capitec Bank to help me reverse the payment, and they charging for it. To make matters worse,they say it will take 7 to 14 working days to get the money back. In the meantime,how does my family survive, how do I pay monthly bills like groceries and school fees. Just because of some stupid technical glitch that is the bank's fault, not mine.
