Airbnb Prepaid Reservation: Give me back my Money!

As a guest, I made a pre-reservation for one night in another city in Poland. (As you already know, you have to prepay for it immediately, even if it is not confirmed). I’ve been waiting for an answer from the host for 24 hours. Unfortunately, the reservation expired. I received a message from Airbnb: the payment for my expired reservation will be in my bank account in 7 business days. As of now (10 working days after the fact) I haven’t received my money for an unconfirmed reservation! Contact with Airbnb in Poland is totally impossible! I’m so mad about it! Please help!
