Hello @Tamara93,
You'll have to contact Airbnb customer service.
This is a forum run by other hosts who can give advice from experience but who don't have access to your reservation informatin.
On the pages where these questions and answers appear, type "contact airbnb" in the "Search the community" search box.
Suggestions will appear as you type. One of them will be "Contact Airbnb: A Community Help Guide".
Click on this and look for the "Contact Airbnb" link in it and click on that.
You can contact them via the website, by phone or by Twitter.
Steve.
