Beware of Aibnb Cancellation Policies

I booked an apartment through Airbnb’s “Superhost” Luka Piscitelli and when I was forced to cancel my entire trip due to unforeseen circumstances, I gave Luka 6 weeks notice, yet he refused to refund 50% of the fee I paid (totalling $236). Despite talking to several supervisors at Airbnb, they refused to help and supported the host because I clicked on something at checkout that says I agreed to this policy (despite my not even remembering seeing that).
