cancellation

Hi. 

I have just made a listing of my vacation home (I am private - non pro). I made the registration via linking to airbnb add. 

However, not all informations  seems to have been syncronized and now I have received a booking for next year which I can't accomondate. 

I can't find any email to booking.com so I can inform them what happend. I have sent an email to the guest, but this is really strange.
