Urgently need FNB help

I'm overseas, and had to repair and reset my iPhone as my battery was replaced. Now I can't reinstall and verify the FNB app, because I can't verify it's really me.

The site isn't any help, either. I can't verify the phone in "Devices and Browsers" because for some reason this is not a verified browser, even though I use it every day.

I also can't contact the team from overseas. (Which raises the question of what I would do, if my phone or card was ****** over here.)

At a loss here. Can someone from FNB contact me back?
