Un Authorised

Today on the 3rd Of June 2015 there was R1511.00 transferd from my Standard Bank Savings account to my tjek account, for my tjek account which was in a overdraft of that amount.Standard Bank did not contact me via sms e mail or telephonicly to inform me of this actions.I Called Standard bank and spoke to Mandla Cindi @ ***who informed me that Standard Bank have to notify me before they can do a internal transfer on my accounts.So i was never informed NOTHING...!!!And the money which was in my savings account was there for a specific emergency as im currently going thru a devorce and the money was there for lawyer fees.NOT FOR STANDARD BANK TO TAKE OR TRANSFER IT WITHOUT MY PERMISSION.I URGE STANDARD BANK TO TRANSFER THAT MONEY ASAP BACK TO MY SAVINGS ACCOUNT AS I HAVE STATED THAT IT IS THERE FOR A OTHER PURPOSE.THIS WAS VERY UNPROFESSIONALLY DONE IN THIS MANNER WITHOUT CONTACTING ME.
