Dear @Neela1, it is a community forum for AirBnb hosts and guests. No Airbnb support representative here. You can contact Airbnb via Help - Contact form, via Twitter, or by phone.
Your phone number is on her reservation itinerary. Her phonenumber is also in your reservationlist. You can also message her via Airbnb email. Offcourse we can not supply those information, see above reply from @Claudiu-Nicolae0
