@Pmi-Matching-Property0 is there any safety-related issue that your previous guests reported to Airbnb or a review that has triggered your listing to be unlisted? These are possible reasons, but I recommend that if Airbnb keeps on telling you it's on investigation and the initial support response does not resolve your issue or if you feel the need for more detailed assistance, you can request to speak with a supervisor or a more senior customer service representative. Hope this helps!
