Hello @Sunyoung2,
You'll have to contact Airbnb to discuss the issue.
This site is one where Airbnb members, like yourself, help each other with advice from their own experience. Members here don't have access to anyone else's account or travel history.
For information on ways to contact Airbnb support type "contact airbnb" in the "Search the community" box on these forum pages where you posted your question. Scroll down a little in the list of suggestions that appears and click on the "Contact Airbnb: A Community Help Guide[UPDATED]" one. That lists phone numbers and ways to contact them via Twitter or Facebook.
Steve.
