Not honest ******

I booked at booking.com, Thorntor property they said I must pay 50% of accommodation money,I did pay R3500Zar at FNB Rosebank mall, before I pay we were communicating via email after I payed no one responded,now booking.com got hold of Thorntor property, they said they won't be able to accommodate us & booking.com says that I must look for another place & check in,when we come back we must email them the invoice,how can I book for an accomodation without my refund,I need my refund ASAP because the people that I'm going with know that on the 1st-3rd April will be on a weekend away,so I want my R3500 Asap.
