@Laura4076 I'm SO sorry this happened to you! I hope you can recover and get going again and give some serious thought to moving to another platform.
You're so right about us hosts having 24 hours (with multiple reminder messages regularly sent) to respond to inquiries, yet AirBnB customer service typically is unreachable, and when reached, unknowledgeable and unresponsive.
This is such a horror story. In a way it's "good" that they also committed the fraud, because it's more likely they'll get caught and perhaps be held accountable for the damage to your house.
Hang in there, and better luck moving forward. Kia
