How can we help u is a joke

Im currently struggling with FNB account that allows unauthorized debit orders to continuously debit money on my bank account on a monthly basis. I received the worst treatment at Zevenwacht FNB branch where i went to report more of the unauthorized debit orders and i was told that they can't do anything about it. I must phone number that does not even exist to stop my debit orders from Telkom and recently Vodacom.
