I actually had a similar problem trying to park in a parking garage. I talked to some people working there (they were moving 'event day price' signs around). I asked if there was a kiosk or any other way to pay (other than by phone). They said there was not and said I just had to leave and find street parking.
This happened when I was trying to park near a place to get my phone fixed!
Over the past year all of the paid parking lots in my city have removed their kiosks and replaced them with QR codes that open a website with a very unwieldy form. Very annoying if your phone happens to be dead or broken or you run out of data or something!
