Been reading alot of posts from Hosts mentioning an issue with Airbnb not paying the referral bonus. I guess you would need to take screen shots of the emails and the referral link you shared with the new Host to prove they used the link to create their listing and send that to Airbnb? Be sure to read through the restrictions regarding the program. Some Hosts are not eligible to receive the bonus:

Maybe some other Hosts can post here who were in the same situation and if they were able to resolve it?
