So sorry this happened...
Not sure what we can assist with as you didn't provide details as to the situation involved? Not sure why Airbnb wouldn't help you get a full refund if you felt threatened for your life? Was law enforcement involved in your situation? Could you provide a copy of the police report to Airbnb? If we had some more information, we could possibly assist more.
Did you actually start the stay at the Airbnb in question, then leave due to security concerns? If so, you can also leave an honest review of the Host on the platform.
You have experienced the same issues with Airbnb CS that Hosts do. I would continue to persist and get a case number you can keep referring back to if they close the case without resolving so the next Agent can review it. It's best to try and reach US-based customer service late in the evening from 7pm onward instead of normal working hours.
