Terrible online banking assistance

I accidentally drove over my phone, it was damaged beyond repair. I got a new phone and tried to set up the FNB banking app.

I cannot setup the app on the new phone because I don't remember my username and password (I used my fingerprint). I cannot reset my username or password because I need to approve it on my old (busted) phone.

I phoned the call center for assistance, they couldn't help me and said I needed to go into the branch. I went into the branch and they said I need to phone the call center, because their phones arent working!!!!!!

I am beyond annoyed and frustrated!!!!!!!

I would switch banks just to have access to my own account again!!
