Victim of online banking *****

I have been a loyal ABSA Malmesbury client for more than 10 years, with several different accounts at this Financial Institution. Yesterday I was a victim of online banking *****. R21 000 ****** out of my account in a few seconds. As soon as I noticed I went to the bank to stop everything and they can clearly see that yes this was such a case. 6 transactions Total R21 000 gone (This is all of my money, left in the account is R440). I opened a case at the police station and completed all the necessary forms at the bank and had to hear that an investigation will be conducted and funds will only be paid back(if any) after 30 days. I can't wait 30 days for MY money. And now they want to tell me i can make loan while I wait. A bank you will think your money is safe but now my family has te suffer. I am the only working person in the house ,have bills to pay and have a one month old baby that I need to take care of. This is highly unacceptable.
