Poor communication

I've booked accomodation at Augrabies through the website, realised that I wanted to drive further on my first day and wanted to rather stay over in Calvinia. I cancelled the accomodation in Augrabies, expecting a refund, and booked at Calvinia paying the full amount up front. Now I was informed via a no-reply email that my refund can be used on my next booking. My next booking, but my next booking was already made and paid in full. I would like my first booking to be refunded. Also, even though I have paid the first booking on Monday, it has not yet reflected as paid. I also have no means of communicating with them.
