Money deducted without notification

The morning after pay day,I wake up to find R1700 deducted from my cheque account. I didn't recognise the company which debited and the amount was random.i received no notification from notify me.after holding on for over half an hour to get hold of absa,I was transferred to three different departments.i was told that they cannot assist me in reversal of this amount.absa credit card deducted this amount from my cheque account without my knowledge.after tears and begging...i was told they are unable to assist.ive been banking with absa for 10yrs and the attitude was disgusting.i am pregnant and I'm in an absolute state.i told them I need that money for my baby's scan but they don't care.im left without money to travel to work and no money for my child's vital scan.disgusting service.no empathy.no assistance.they transferred me from department to department without even notifying me I was being transferred.absa did not notify me that they would be deducted this huge chunk out of my salary.it was so bad that I was unable to talk through the tears and was told to calm down.it has put a huge stress onto my pregnancy and my lively hood.
