Bank details

Hi

I would like to ask how can I add my bank details in my profile as a owner of a property which I have just listed on booking.com

When I try to do it, it ask me for a PIN code but I couldn't get this PIN number as I don't receive any SMS of phone call that I am supposed to receive.

When I call booking.com is asking for a PIN code that I don't have either.

Anyone can help?
