Paying for something that i never authorized.

I called the Std bank business help desk yesterday with a complain about the different insurance companies debiting my account for the past two months that i have opened it. i have been charged unpaid debit fees for something i know nothing about. the consultant that i spoke to yesterday told me to go & do my own investigation as to who is debiting & why. & that it was not the bank's responsibility to find out for me. i told her, i'm being de*****ed & the bank is not assisting me with anything. One of the security question was DO YOU HAVE A DEBIT ORDER IN THIS ACCOUNT & I SAID NO AND I WAS TOLD I PASSED ALL MY SECURITY QUESTIONS. But a debit order went through. My husband had the same problem a few months ago & the debit on his account was reversed & he was told that the account number was used by someone who had tracker before it was given to him. i want to close both the accounts(personal & business) that i have with Std bank ASAP & move them to a bank that cares about their clients. I wonder if ********** are hacking into the Std bank system to de***** us. The bank should protect us from ********** NOT JUST ENJOY OUR MONEY THROUGH THE CHARGES THEY MAKE FROM US.
