Host tried to rip us off. Two months later, no refund.

A friend and I booked a property for two nights in Salamanca, Spain. The price was 30 Euros a night. After we had stayed one night, the host told us that she had made a mistake on the listing and the price was per person per night. There was nothing wrong with the property; it was in a good location and clean. However, having spent two months traveling in Europe this summer, it was most certainly not a 60-euro room. We told the host that this was outside our budget and she told us we had to pay her 60 euros or leave. We checked out and found another property straight away. When I applied for a refund, the host rejected it, saying we had not left the property until 3:00 PM. I have messages through Airbnb to our new host at noon asking if we could come early, as we were on the street with our bags. Airbnb has never followed up. Two months late, and we still have no refund.
