Removing an API from My Hub that was created from expired trial account

Someone in my Company  started a trial account, created a small sample, and added me as a collaborator on it.  Now the account has expired and we're not going to use that account any more.  How do I remove the API from the My Hub page - I don't see any way to remove it.  If I click on it, I get the error message "Error.This API is blocked. Please contact the API owner for more information."
