New Listing - Urgent - getting double booked
Hi, i have an apartment and am currently listed with Airbnb and Trip Advisor, and just joined Booking.com. Although my calendars linked, today i got a booking which is already booked via Airbnb. I think its something to do with my calendar showing all the bookings from airbnb, but also says "1 left to sell" which cuts across all my dates, although i only have one apartment! please help before i get anymore double bookings, and what do i do about the guest who has just booked??
