Standardbank worse bank ever

This bank is the worse i know....ive been banking with them all my life. 4years ago I sent e-mail and informed them on the phone i am unemployed. Lately they sit and watch all my accounts and whatever money there is in any account they just take it. Without my consent. I borrow money from family to provide for my children and then they just take my money. I'm sorry but they don't have any consent to debit my savings account as they please, I am making a case of theft and they will answer why they took money for 3months now without my permission after I told them as soon as I get a job i will repay all the minus ammount on my accounts
