I would like to pay for a room, but I cannot register as a new user. Airbnb says that the SMS was sent, but I didn't receive it. I am from Slovenia. The error is not on my side because I tried everything: all forms of my number, other numbers, calls, Facebook login, different browsers and app, different days etc. Verification with WhatsApp worked, but I'm still not allowed to register. I tried calling the phone number is USA (expensive) and couldn't get pass the answering machine. There seems to be no other way to get support. Can anyone here help?
