Bad service and non user friendly app

Because of tge user-friendlyness of tge FNB app,I suffered Immense financial prejudice. Several times I would make payments and wait for it to reflect only to discover payments didn't go thru. On numerous occasions I select send POP but nothing comes thru. I can't speak to a consultant and even the automated consultant doesn't respond. There's no direct phone number and u don't know who's on the other end. I have screenshots of non response if required. I'm.not happy,considering that I pay thousands of Rands in bank fees(can be proved and provided)
