Just opened a new FNB account and many of the necessary functions are not working

Just opened a new FNB account and many of the necessary functions are not working. No one can tell me why. I spent 6 hours today on their messaging app and half an hour on a call being passed from one person to the next. Eventually the last person told me that they can't fix it. So I'm stuck with a business account that does not function. Really really poor service
