FNB - How CAN you help me? I'd really like to know.

I have always been a fan & promotor of FNB and for the most part I still really enjoy and believe in the brand and products they offer. But the service I have been receiving when I have questions or need help or direction is beyond shocking. For the last 6 days I have been trying to contact their collections department to ask them to re run two debits as the funds were and are available but were returned for some unknown reason. I have spent hours being transferred from department to department as no one knew who I need tog go through to (each obviously must have thought they knew) and each time I reached the collections department the call would cut. So I tried emailing; the debit orders department said they could not help me. They gave me the collections email WHICH DOES NOT WORK. I even tried to talk to someone on the secure chat on the app and after wasting about an hour was told to call the same number I have been trying for 6 days. This is shocking service FNB. I feel forced to use this avenue to let people know what they are in for.
