Hello @Alexa20,
Do you mean the terms as mentioned in a phrase like "by continuing you agree to our terms of service" ?
If so then these may be the ones you want https://www.airbnb.com/terms
If you click on "Help" and then on "Visit the help centre" and then on "Contact us" at the bottom you'll see a page that gives contact options, including a phone number.
You can also type "contact airbnb" in the "Search the community" box on these pages where you posted your question. Click on the "Contact Airbnb: A Community Help Guide" suggestion when it appears.
Steve.
