PATHETIC SERVICE!!!!!!

After numerous calls since the beginning of October and logging a debit order reversal on the FNB app, to date there is no feedback from FNB. The premier banking consultants cannot assist with the debit order reversal anymore. They keep you on hold for more than 30 minutes and eventually the phone gets disconnected. If my bank cannot assist me with this small issue, what I am supposed to do. FNB your service has been very poor lately. I am not a happy customer at the moment and I am even considering moving banks.
