FNB Debit Order Dispute Process is problematic

I am tired of this FNB issue regarding these unauthorised debit orders. I am trying to dispute it by calling them but as it stands I have been holding for 30 minutes. I thought that our information was meant to be secure with them and that our money is secure as well but instead we have to suffer at their gain because we get charged for all of these reversals. I tried to reverse this using the APP, Cellphone banking and I tried online and I keep getting an error message.

I joined FNB Because I thought they were secure and competent but thus far I am unimpressed by their service due to this experience. 35 minutes and counting, they wont even reimburse me for my airtime that I am spending whilst holding on this line.
