No response to query

I have a problem with bookings, I did send emails but to no avail, I just get no response from anybody. I made a booking at Dikhololo, I was redirected to the agoda website and I didn't see that my dates was changed in the process, so I booked the incorrect dates. On the site it says if you make an incorrect booking, you have to rebook and ask for a refund on the incorrect booking, which I did. When I booked the correct dates, my booking was doubled. So now I paid for two nights and the money is just in the water, nobody responds to my emails, I am just being ignored. On the booking confirmation was an email address from the holiday club, the lady forwarded my email to two other ladies at beekmangroup, but it seems like the buck is just getting passed on, nobody wants to take responsibility.
