FNB Bank approves ********** transactions and unable to resolve queries

FNB Bank approves ********** debit orders without my permission/approval and I didn't even receive a new debit order notification. When I call my FNB Bank to query, I am being sent from pillar to post "***** Unit who is unable to help as they claim to work with transactional ***** only not "Debit Orders *****" then send me back to accounts, accounts department says, unfortunately, the is nothing a bank can do "LIKE REALLY NOW" .....I am frustrated and don't know what to do. This is the 2nd time new debit orders happening in 2 months consecutively, yet FNB is allowing these *****s on my account after I have reported. FNB customer services is extremely poor and ridiculous, FNB ITS THE WORST BANK EVER
