Airbnb Did Not Respond to My Message for a Refund

I was looking for a place to stay for one night in Pljevlja, Montenegro, on my way back from Budva to Sarajevo. I rented a house that said it was 3 km from the center. It turned out to be 4 km from Palez, not Plevlja. It was 40 km from my route, which is even further. I had a flight in a day. I didn't want to waste any time, so I immediately canceled my reservation and received a refund from the host. However, Airbnb isn't responding to my messages or issuing a refund.
