UNACCEPTABLE - WITHOUT PERMISSION - BANK JOURNALS DONE ON MY PERSONAL ACCOUNT

I've been a loyal Absa customer all my life and today I will close my bank account and never ever will I make use of this pathetic ******** service. It is unacceptable and ******** to take money without permission and knowledge from an individual's bank account. Yesterday I did a purchase, when i saw a R3000 missing from my bank account, I checked online there was a journal done and phoned the bank customer service immediately. This journal is done not on the 1st or 31st or 15th but on the 20th when Absa pays they staff how ironic. The collections department said they CAN take any amount of money in your bank account if you owe the bank money? How the hell can this be legal?? How can you tell a client this??? Its ********, its *****, and *********!! So you telling me any company can view into their debtors accounts without permission and decide what they want and not what the client can give!!! ****!! I work in Finance I know how payments work! ABSA I want my money refunded with immediate effect !! And i will not wait 48hrs for you to decide to refund this money!!
