Hello @Rishav1,
This is a site where Airbnb members help each other with advice from their own experience. It's not Airbnb support.
You can find ways to contact support as follows.
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.
