lost of income

Standard bank took my entire salary out of my standard bank account without my consent to settle an account that they created that went into arrears! Not my fault and now none of the debit orders went through! Putting me in dept of my veichle and home! Never heard that this kind of thing is legal to just transfer a persons salary into another account! Since the beginning of the month i stuggle to sort this problem with them to get my salary back!
