Beware SANPARKS ... NO customer service

Hello Hellopeter I recently reserved online for accommodation with SANPARKS and unlike in the past, immediately had to pay. That's not the problem. 47 days before the trip I had to make a change to reduce the number of huts and one visitor...and was levied a fee of more than the 25% charged for changes between 15 and 30 days before the trip There is no logic in the amended fees and no explanation. On requesting info by email, I got an automated reply saying, that I would get a reply within 10 work days... now 19 days in total and NO reply. I wrote again but NO reply. I have spent well over an hour on the phone to customer care and head office but NO reply. There is also no response on how to get ones refund? What has happened to SANPARKS?
