Appalling service

I wrote to KZN wildlife and asked for a quote for camping at two of their reserves. I gave details of the dates we wanted to stay and where. A week later I received a quote, and then emailed the reservation office to confirm the booking. It was only after paying that I checked my initial email giving the cost, that I discovered I;d paid more than I was quoted. When I queried this,I was informed that because we were going in peak season, it cost more. I quoted the email I received, but that was beside the point. Problem number two: On their their booking forms the information is totally our of sync with the printed sheet, so it's really difficult to check what's what. When I did manage to decipher their form, I discovered that despite having carefully specified days and dates we wanted, they had booked us for an extra night. After sending a number of emails which went unanswered I managed to get them to admit they'd made a mistake and that I was due for a refund. Despite numerous emails, none of which have been answered, two weeks down the line we are still out of pocket.
