@Tracey136 to contact Airbnb:
On your Help page, near the bottom right is a "Contact us" button.
Or you can use this link: https://www.airbnb.com/help/contact_us
Once you are on the "Contact us" page, choose "Its something else"
This will give you the choice to either exchange messages with AirBnB or to speak to someone on the phone.
(Using the "Contact us" by phone gives you the option to have them call you, so you don't have to wait on hold.)
If you don't mind waiting on the phone:
