Missing funds

Good evening,My name is Johannah and I'm posting this on behalf of my older sister.On the 2nd of March,my sister received a notification of overnight transaction payment of R1926 debit order from Nedbank.when she went to bank to find out what happened to the missing money,1st thy told her that it was ackermans then 2nd time they said my sister took a credit card.I called head office and there was this lady who was rude to me and we have been go to Alexandra branch but nothing is happening.Thy have asked my sister to bring affidavity so that thy can sent it to Head office for the investigation.I have been asking my self some questions on how peoples money goes missing almost everyday in the banks.As for Nedbank,please be advised that with the ***** that is going on inside the banks you going to lose lots of customers. I have asked my lawyer to assist my sister on this matter because we have ***** like you Nedbank *****ing our money so I won't rest until my sister get her money
