STANDARDBANK SECURITY SYSTEMS ARE QUESTIONABLE

Last night at about 11.33 PM I missed a called from a 0800 number and then a debit of R1706.49 went through on my account. 2 minutes later another R1706.49 was debited as I received an sms. I call ed the bank ***** division and I was told that this was an international withdrawal from Malaysia and they called me on the 08000 number in order for me to authorize the withdrawal. I never picked and funny enough the bank authorized the withdrawal which was done in a country outside of South Africa. I have never even been outside of South Africa and did not inform the bank that I will be going outside of South Africa, Further to this the person advised me that an investigation will take 6 working days. I need my money back and cannot go even a day without it. I need to pay bills as it is Month End and will appreciate if you can bring closure to this and get my money back into my account.
