No customer service at all

I am to say the least up hauled by the service received from FNB. I am trying to reverse a debit order ( which the third party has already been paid for) I tried using the online app where they purely refuse to help me. I have gone through both me and my husbands talking minutes just to get through to someone, just to be transferred again and cut off. I eventually decided to get in my car and go to FNB and how convenient it is the only bank in the mall that is closed. I honestly cannot believe the lack of customer service received. First the person on the message app tells me I need to do it myself on the app, where after I told them it is not reflecting on my debit orders. The second person just tells me straight sorry he cannot assist. After phoning roughly 10 times nobody has as much as tried to assist me. After being a loyal customer for so long I think I will be taking my business elsewhere, where customer service is still a priority.
