Ticket from David Petkovsek - Certification Exam

I was registered for a HUD Housing exam today at 1pm. I set up and made sure I could get in earlier and everything was good. At exam time the two factor authentication would not send a code and I could not get in. I contacted the Kryterion Support and they said that I needed to contact HudHousing for that. Can I get assistance and reschedule? thanks, Dave Petkovsek 386-627-3182
