Left feeling embarrassed and hopeless due to ABSA

On the 6th of April at around 6 pm I swiped my credit card at checkers to purchase groceries. It declined, so we swiped again. It declined again. Being positive that there was funds I kept swiping as the line was growing at the till and so was my embarrassment. Eventually I started receiving multiple sms's saying the money was being taken off to the point that it cleared all the funds out my account. The lady at the teller said the money should be reversed so I decided to logon to my banking app and transfer money onto my credit card to swipe again. Then my banking app said it was offline due to scheduled maintenance. Who does maintenance at that time while people are using their cards and banking apps? shouldn't this be done at the dead of night? I proceeded to call ABSA customer care number as a last resort. After waiting 17 min to get an answer the ABSA representative told me she can do nothing and i must just wait till the problem is resolved. The store was closing and i needed the groceries to make dinner for my family. ABSA rep then said i must go home and it will be resolved in the morning. I mean what kind of an answer is that when i am in distress that i cant use any form of my money due to ABSA being offline. I even tried using the ATM which didn't work. After much embarrassment i had to call my wife to come pay all the way from our house!!! I've been a client of ABSA for more than 15 years, had home loans, personal loans and credit cards with ABSA. I cant even describe how i feel about what happened. I will make it a point to change bank accounts and take this matter further from the embarrassment i felt due to your scheduled maintenance which i was not informed of in any way shape or form!
