Lack of response to emails and obtaining refund

I booked our holiday in Jan 2015 and renegotiated the payment terms to 50% deposit payable immediately to secure the booking and the balance to be paid at the end of Jan 2015. Received confirmation almost immediately from Safarinow, I paid and booked. A couple days prior to our departure (approx. 2 weeks ago) I saw something on Google Earth and had huge safety concerns. I made contact with the contact person of the unit and notified Safarinow requesting Safarinow to stand-down until I need them to intervene if the owner is reluctant to refund us the 50% as per the terms. Safarinow rep**** to these emails with no hassle. However, when I expressed my 1st issue that it seems the owner is reluctant to refund on the 12Mar15 and then confirmed this on the 13Mar15, NO ONE from Safarinow has rep**** with a solution on how to assist in getting our 50% refund. We've been sitting at home for the past 2 weeks as we cancelled our accommodation due to the safety concern. The right thing to do is to refund us the 50% so we can at least try and go somewhere else for a long weekend at least!!!!
