bidvest bank *****ing your money

I bank with Bidvest bank and this is a nightmare doing business with them. They debit your account without any authorisation, they allow third parties to debit your account without authorisation, they debit your account for any reason and without any notification. When trying to get support and or assistance to query all unauthorised debits on your account, you are simply ignored and not answered and assisted. I have sent umpteenth emails to support, the CEO, an employee, customer service, no replies, no help, nothing. It is as if the lights are on but no one is home. This is probably how they '*****' money from clients, they go on a hunting spree in your account and debit monies only to then turn a blind eye on you, you cannot get any help and or assistance.
